-//  2024-05-07: OpenGL: Update loader for Linux to support EGL/GLVND. (#7562)
-//  2024-04-16: OpenGL: Detect ES3 contexts on desktop based on version string, to e.g. avoid calling glPolygonMode() on them. (#7447)
 //  2024-01-09: OpenGL: Update GL3W based imgui_impl_opengl3_loader.h to load "libGL.so" and variants, fixing regression on distros missing a symlink.
 //  2023-11-08: OpenGL: Update GL3W based imgui_impl_opengl3_loader.h to load "libGL.so" instead of "libGL.so.1", accommodating for NetBSD systems having only "libGL.so.3" available. (#6983)
 //  2023-10-05: OpenGL: Rename symbols in our internal loader so that LTO compilation with another copy of gl3w is possible. (#6875, #6668, #4445)

- VERSION 1.91.3 (Released 2024-10-04)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.91.3
-
-Breaking changes:
-
-- Drags: treat v_min==v_max as a valid clamping range when != 0.0f. Zero is still a special
-  value due to legacy reasons, unless using ImGuiSliderFlags_ClampZeroRange. (#7968, #3361, #76)
-- Drags: extended behavior of ImGuiSliderFlags_AlwaysClamp to include _ClampZeroRange.
-  It considers v_min==v_max==0.0f as a valid clamping range (aka edits not allowed).
-  Although unlikely, it you wish to only clamp on text input but want v_min==v_max==0.0f
-  to mean unclamped drags, you can use _ClampOnInput instead of _AlwaysClamp. (#7968, #3361, #76)
-
-Other changes:
-
-- Error Handling: Enabled/improved error recovery systems. (#1651, #5654)
-  - Error recovery is provided as a way to facilitate:
-    - Recovery after a programming error. Native code or scripting language (the later
-      tends to facilitate iterating on code while running).
-    - Recovery after running an exception handler or any error processing which may skip code
-      after an error has been detected.
-  - Error recovery is not perfect nor guaranteed! It is a feature to ease development.
-    You not are not supposed to rely on it in the course of a normal application run.
-  - Functions that support error recovery are using IM_ASSERT_USER_ERROR() instead of IM_ASSERT().
-  - By design, we do not allow error recovery to be 100% silent. One of the options needs to be enabled!
-  - Possible usage: facilitate recovery from errors triggered from a scripting language or
-    after specific exceptions handlers. Surface errors to programmers in less aggressive ways.
-  - Always ensure that on programmers seats you have at minimum Asserts or Tooltips enabled
-    when making direct imgui API calls! Otherwise it would severely hinder your ability to
-    catch and correct mistakes!
-  - Added io.ConfigErrorRecovery to enable error recovery support.
-  - Added io.ConfigErrorRecoveryEnableAssert to assert on recoverable errors.
-  - Added io.ConfigErrorRecoveryEnableDebugLog to output to debug log on recoverable errors.
-  - Added io.ConfigErrorRecoveryEnableTooltip to enable displaying an error tooltip on recoverable errors.
-    The tooltip include a way to enable asserts if they were disabled.
-  - All options are enabled by default.
-  - Read https://github.com/ocornut/imgui/wiki/Error-Handling for a bit more details.
-- Windows: BeginChild(): made it possible to call SetNextWindowSize() on a child window
-  using ImGuiChildFlags_ResizeX,ImGuiChildFlags_ResizeY in order to override its current
-  size. (#1710, #8020)
-- Scrollbar: Shift+Click scroll to clicked location (pre-1.90.8 default). (#8002, #7328)
-- Scrollbar: added io.ConfigScrollbarScrollByPage setting (default to true). (#8002, #7328)
-  Set io.ConfigScrollbarScrollByPage=false to enforce always scrolling to clicked location.
-- Drags: split ImGuiSliderFlags_AlwaysClamp into two distinct flags: (#7968, #3361, #76)
-  - ImGuiSliderFlags_AlwaysClamp = ImGuiSliderFlags_ClampOnInput + ImGuiSliderFlags_ClampZeroRange.
-  - Previously _AlwaysClamp only did the equivalent of _ClampOnInput.
-  - Added ImGuiSliderFlags_ClampOnInput which is now a subset of AlwaysClamp.
-    (note that it was the old name of AlwaysClamp, but we are reintroducing that name).
-  - Added ImGuiSliderFlags_ClampZeroRange to enforce clamping even when v_min==v_max==0.0f
-    in drag functions. Sliders are not affected.
-- Tooltips, Drag and Drop: Fixed an issue where the fallback drag and drop payload tooltip
-  appeared during drag and drop release.
-- Tooltips, Drag and Drop: Stabilized name of drag and drop tooltip window so that
-  transitioning from an item tooltip to a drag tooltip doesn't leak window auto-sizing
-  info from one to the other. (#8036)
-- Tooltips: Tooltips triggered from touch inputs are positioned above the item. (#8036)
-- Backends: SDL3: Update for API changes: SDL_bool removal. SDL_INIT_TIMER removal.
-- Backends: WebGPU: Fixed DAWN api change using WGPUStringView in WGPUShaderSourceWGSL.

- VERSION 1.91.2 (Released 2024-09-19)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.91.2
-
-Breaking changes:
-
- - Internals: using multiple overlayed ButtonBehavior() with same ID will now have the
-   io.ConfigDebugHighlightIdConflicts=true feature emit a warning. (#8030)
-   It was one of the rare case where using same ID is legal. Workarounds:
-   - use single ButtonBehavior() call with multiple _MouseButton flags
-   - or surround the calls with PushItemFlag(ImGuiItemFlags_AllowDuplicateId, true); ... PopItemFlag()
-
-Other changes:
-
-- Added io.ConfigDebugHighlightIdConflicts debug feature! (#7961, #7669)
-  THIS DETECTS THE MOST COMMON USER ERROR BY FIRST-TIME DEAR IMGUI PROGRAMMERS!
-  - The tool detects when multiple items are sharing the same identifier, due to not
-    using PushID/PopID in loops, or not using ID stack facilities such as "##" suffixes.
-    Very frequently it happens when using empty "" labels.
-  - When hovering an item with a conflicting ID, all visible items with the same ID will
-    be highlighted and an explanatory tooltip is made visible.
-  - The feature may be disabled and is exposed in Demo->Tools menu.
-  - I've been wanting to add this tool for a long time, but was stalled by finding a way to
-    not make it spammy + make it practically zero cost. After @pthom made various proposals to
-    solve the same problem (thanks for pushing me!), I decided it was time to finish it.
-  - Added ImGuiItemFlags_AllowDuplicateId to use with PushItemFlag()/PopItemFlag() if for some
-    reason you intend to have duplicate identifiers.

-     #7472, #7581, #7724, #7926, #7937 and probably more..)
-- Nav: pressing any keyboard key while holding Alt disable toggling nav layer on Alt release. (#4439)
-- MultiSelect+Tables: fixed an issue where box-select would skip items while drag-scrolling
-  in a table with outer borders. (#7970, #7821).
-- Inputs: SetNextItemShortcut() with ImGuiInputFlags_Tooltip doesn't show tooltip when item is active.
-- InputText: internal refactoring to simplify and optimize the code. The ImWchar buffer has been
-  removed. Simplifications allowed to implement new optimizations for handling very large text buffers
-  (e.g. in our testing, handling of a 1 MB text buffer is now 3 times faster in VS2022 Debug build).
-  This is the first step toward more refactoring. (#7925) [@alektron, @ocornut]
-- InputText: added CJK double-width punctuation to list of separators considered for CTRL+Arrow.
-- Tables: fixed auto-width columns when using synced-instances of same table. The previous fix
-  done in v1.90.5 was incomplete. (#7218)
-- Tables: fixed assertion related to inconsistent outer clipping when sizes are not rounded. (#7957) [@eclbtownsend]
-- Tables: fixed assertion with tables with borders when clipped by parent. (#6765, #3752, #7428)
-- Windows: fixed an issue where double-click to collapse could be triggered even while another
-  item is active, if the item didn't use the left mouse button. (#7841)
-- Misc: Made it accepted to call SetMouseCursor() with any out-of-bound value, as a way to allow
-  hacking in custom cursors if desirable.
-- Fonts: fixed ellipsis "..." rendering width miscalculation bug introduced in 1.91.0. (#7976) [@DDeimos]
-- TextLinkOpenURL(): modified tooltip to display a verb "Open 'xxxx'". (#7885, #7660)
-- Backends: SDL2: use SDL_Vulkan_GetDrawableSize() when available. (#7967, #3190) [@scribam]
-- Backends: GLFW+Emscripten: use OSX behaviors automatically when using contrib glfw port. (#7965, #7915)
-  [@ypujante]
-- Backends: WebGPU: Added support for optional IMGUI_IMPL_WEBGPU_BACKEND_DAWN / IMGUI_IMPL_WEBGPU_BACKEND_WGPU
-  defines to handle ever-changing native implementations. (#7977, #7969, #6602, #6188, #7523) [@acgaudette]

------------------------------------------------------------------------
- VERSION 1.91.1 (Released 2024-09-04)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.91.1
-
-Breaking changes:
-
-- BeginChild(): renamed ImGuiChildFlags_Border to ImGuiChildFlags_Borders for consistency. [@cfillion]
-  Kept inline redirection flag (will obsolete).
-- IO: moved clipboard functions from ImGuiIO to ImGuiPlatformIO:
-    - io.GetClipboardTextFn         -> platform_io.Platform_GetClipboardTextFn
-    - io.SetClipboardTextFn         -> platform_io.Platform_SetClipboardTextFn
-    - in function signatures, changed 'void* user_data' to 'ImGuiContext* ctx' for consistency
-      with other functions. Pull your user data from platform_io.ClipboardUserData if used.
-    - as this is will affect all users of custom engines/backends, we are providing proper
-      legacy redirection (will obsolete).
-- IO: moved other functions from ImGuiIO to ImGuiPlatformIO:
-    - io.PlatformOpenInShellFn      -> platform_io.Platform_OpenInShellFn (#7660)
-    - io.PlatformSetImeDataFn       -> platform_io.Platform_SetImeDataFn
-    - io.PlatformLocaleDecimalPoint -> platform_io.Platform_LocaleDecimalPoint (#7389, #6719, #2278)
-    - access those via GetPlatformIO() instead of GetIO().
-  (Because PlatformOpenInShellFn and PlatformSetImeDataFn were introduced very recently and
-  often automatically set by core library and backends, we are exceptionally not maintaining
-  a legacy redirection symbol for those two.)
-- Commented the old ImageButton() signature obsoleted in 1.89 (~August 2022). (#5533, #4471, #2464, #1390)
-   - old ImageButton() used ImTextureId as item id (created issue with e.g. multiple buttons in same scope, transient texture id values, opaque computation of ID)
-   - new ImageButton() requires an explicit 'const char* str_id'
-   - old ImageButton() had frame_padding' override argument.
-   - new ImageButton() always use style.FramePadding, which you can modify using PushStyleVar()/PopStyleVar().
-
-Other changes:
-
-- IO: Added GetPlatformIO() and ImGuiPlatformIO, pulled from 'docking' branch, which
-  is a centralized spot to connect os/platform/renderer related functions.
-  Clipboard, IME and OpenInShell hooks are moved here. (#7660)
-- IO, InputText: fixed an issue where typing text in an InputText() would defer character
-  processing by one frame, because of the trickling input queue. Reworked interleaved
-  keys<>char trickling to take account for keys known to input characters. (#7889, #4921, #4858)
-- Windows: adjust default ClipRect to better match rendering of thick borders (which are in
-  theory not supported). Compensate for the fact that borders are centered around the windows
-  edge rather than inner. (#7887, #7888 + #3312, #7540, #3756, #6170, #6365)
-- Made BeginItemTooltip() and IsItemHovered() with delay flag infer an implicit ID (for
-  ID-less items such as Text element) in a way that works when item resizes. (#7945, #1485)
-- MultiSelect+TreeNode+Drag and Drop: fixed an issue where carrying a drag and drop payload
-  over an already open tree node using multi-select would incorrectly select it. (#7850)
-- MultiSelect+TreeNode: default open behavior is _OpenOnDoubleClick + _OpenOnArrow when
-  used in a multi-select context without any ImGuiTreeNode_OpenOnXXX flags set. (#7850)
-- Tables: fixes/revert a 1.90 change were outer border would be moved bottom and right
-  by an extra pixel + rework the change so that contents doesn't overlap the bottom and
-  right border in a scrolling table. (#6765, #3752, #7428)
-- Tables: fixed an issue resizing columns or querying hovered column/row when using multiple
-  synched instances that are layed out at different X positions. (#7933)
-- Tabs: avoid queuing a refocus when tab is already focused, which would have the
-  side-effect of e.g. closing popup on a mouse release. (#7914)
-- InputText: allow callback to update buffer while in read-only mode. (imgui_club/#46)
-- InputText: fixed an issue programmatically refocusing a multi-line input which was just active. (#4761, #7870)
-- TextLink(), TextLinkOpenURL(): change mouse cursor to Hand shape when hovered. (#7885, #7660)
-- Tooltips, Drag and Drop: made it possible to override BeginTooltip() position while inside
-  a drag and drop source or target: a SetNextWindowPos() call won't be overridden. (#6973)
-- PlotHistogram, PlotLines: register item ID and use button behavior in a more idiomatic manner,
-  fixes preventing e.g. GetItemID() and other ID-based helper to work. (#7935, #3072)
-- Style: added PushStyleVarX(), PushStyleVarY() helpers to conveniently modify only
-  one component of a ImVec2 var.
-- Fonts: made it possible to use PushFont()/PopFont() calls across Begin() calls. (#3224, #3875, #6398, #7903)
-- Backends:
-  - Backends: GLFW: added ImGui_ImplGlfw_Sleep() helper function because GLFW does not
-    provide a way to do a portable sleep. (#7844)
-  - Backends: GLFW+Emscripten: Use OpenURL() from GLFW3 contrib port when available and using
-    the contrib port instead of Emscripten own GLFW3 implementation. (#7647, #7915, #7660) [@ypujante]
-  - Backends: SDL2, SDL3: ignore events of other SDL windows. (#7853) [@madebr, @ocornut]
-  - Backends: SDL2, SDL3: storing SDL_WindowID inside ImGuiViewport::PlatformHandle instead of SDL_Window*.
-  - Backends: SDL3: Update for API changes: SDL_GetGamepads() memory ownership logic was reverted back
-    by SDL3 on July 27. (#7918, #7898, #7807) [@cheyao, @MattGuerrette]
-  - Backends: GLFW: passing null window to glfwGetClipboardString()/glfwSetClipboardString()
-    since GLFW own tests are doing that and it seems unnecessary.
-  - Backends: SDL2, SDL3, GLFW, OSX, Allegro: update to set function handlers in ImGuiPlatformIO
-    instead of ImGuiIO.
-- Examples:
-  - Examples: GLFW (all), SDL2 (all), SDL3 (all), Win32+OpenGL3: rework examples main loop
-    to handle minimization without burning CPU or GPU by running unthrottled code. (#7844)
-  - Examples: SDL3: Update for API changes: SDL_Init() returns 0 on failure.
-
------------------------------------------------------------------------
- VERSION 1.91.0 (Released 2024-07-30)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.91.0
-
-Breaking changes:
-
-- IO, IME: renamed platform IME hook and added explicit context for consistency and future-proofness.
-    - old: io.SetPlatformImeDataFn(ImGuiViewport* viewport, ImGuiPlatformImeData* data);
-    - new: io.PlatformSetImeDataFn(ImGuiContext* ctx, ImGuiViewport* viewport, ImGuiPlatformImeData* data);
-  It is expected that for a vast majority of users this is automatically set by core
-  library and/or platform backend so it won't have any effect.
-- Obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax(). (#7838)
-  You should never need those functions! You can do everything in less a confusing manner by only
-  using GetCursorScreenPos() and GetContentRegionAvail(). Also always consider that if you are using
-  GetWindowPos() and GetCursorPos() you may also be making things unnecessarily complicated.
-  I repeat: You can do everything with GetCursorScreenPos() and GetContentRegionAvail()!
-   - GetWindowContentRegionMax().x - GetCursorPos().x              -->  GetContentRegionAvail().x
-   - GetWindowContentRegionMax().x + GetWindowPos().x              -->  GetCursorScreenPos().x + GetContentRegionAvail().x              // when called from left edge of window
-   - GetContentRegionMax()                                         -->  GetContentRegionAvail() + GetCursorScreenPos() - GetWindowPos() // right edge in local coordinates
-   - GetWindowContentRegionMax().x - GetWindowContentRegionMin().x -->  GetContentRegionAvail()                                         // when called from left edge of window
-- Item flag changes:
-  - Obsoleted PushButtonRepeat()/PopButtonRepeat() in favor of using new PushItemFlag()/PopItemFlag()
-    with ImGuiItemFlags_ButtonRepeat. Kept inline redirecting functions (will obsolete).
-  - Obsoleted PushTabStop()/PopTabStop() in favor of using new PushItemFlag()/PopItemFlag()
-    with ImGuiItemFlags_NoTabStop. Kept inline redirecting functions (will obsolete).
-  - Renamed ImGuiSelectableFlags_DontClosePopups to ImGuiSelectableFlags_NoAutoClosePopups for
-    consistency. Kept inline redirecting functions (will obsolete).
-    + Internals: changed/inverted ImGuiItemFlags_SelectableDontClosePopup (default==false) to
-      ImGuiItemFlags_AutoClosePopups (default==true), same logic, only inverted behavior.
-    (#1379, #1468, #2200, #4936, #5216, #7302, #7573)
-- Commented out obsolete ImGuiModFlags (renamed to ImGuiKeyChord in 1.89). (#4921, #456)
-- Commented out obsolete ImGuiModFlags_XXX values (renamed to ImGuiMod_XXX in 1.89). (#4921, #456)
-    - ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl, ImGuiModFlags_Shift -> ImGuiMod_Shift etc.
-- Backends: GLFW+Emscripten: Renamed ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to
-  ImGui_ImplGlfw_InstallEmscriptenCallbacks(), with an additional GLFWWindow* parameter. (#7647) [@ypujante]
-
-Other changes:
-
-- Added TextLink(), TextLinkOpenURL() hyperlink widgets. (#7660)
-- IO: added io.PlatformOpenInShellFn handler to open a link/folder/file in OS shell. (#7660)
-  (*EDIT* From next version 1.91.1 we moved this to platform_io.Platform_OpenInShellFn *EDIT**)
-  Added IMGUI_DISABLE_DEFAULT_SHELL_FUNCTIONS to disable default Windows/Linux/Mac implementations.
-- IO: added io.ConfigNavSwapGamepadButtons to swap Activate/Cancel (A<>B) buttons, to match the
-  typical "Nintendo/Japanese consoles" button layout when using Gamepad navigation. (#787, #5723)
-- Added PushItemFlag()/PopItemFlags(), ImGuiItemFlags to modify shared item flags:
-   - Added ImGuiItemFlags_NoTabStop to disable tabbing through items.
-   - Added ImGuiItemFlags_NoNav to disable any navigation and focus of items. (#787)
-   - Added ImGuiItemFlags_NoNavDefaultFocus to disable item being default focus. (#787)
-   - Added ImGuiItemFlags_ButtonRepeat to enable repeat on any button-like behavior.
-   - Added ImGuiItemFlags_AutoClosePopups to disable menu items/selection auto closing parent popups.
-     Disabling this was previously possible for Selectable() via a direct flag but not for MenuItem().
-     (#1379, #1468, #2200, #4936, #5216, #7302, #7573)
-   - This was mostly all previously in imgui_internal.h.
-- Multi-Select: added multi-select API and demos. (#1861, #6518)
-   - This system implements standard multi-selection idioms (CTRL+mouse click, CTRL+keyboard moves,
-     SHIFT+mouse click, SHIFT+keyboard moves, etc.) with support for clipper (not submitting non-visible
-     items), box-selection with scrolling, and many other details.
-   - In the spirit of Dear ImGui design, your code owns both items and actual selection data.
-     This is designed to allow all kinds of selection storage you may use in your application
-     (e.g. set/map/hash, intrusive selection, interval trees, up to you).
-   - The supported widgets are Selectable(), Checkbox(). TreeNode() is also technically supported but...
-     using this correctly is more complicated. You need some sort of linear/random access to your tree,
-     which is suited to advanced trees setups already implementing filters and clipper.
-     We will work toward simplifying our existing demo for trees.
-   - A helper ImGuiSelectionBasicStorage is provided to facilitate getting started in a typical app
-     (likely to suit a majority of users).
-   - Documentation:
-     - Wiki page https://github.com/ocornut/imgui/wiki/Multi-Select for API overview.
-     - Demo code + headers are well commented.
-  - Added BeginMultiSelect(), EndMultiSelect(), SetNextItemSelectionUserData().
-  - Added IsItemToggledSelection() for use if you need latest selection update during current iteration.
-  - Added ImGuiMultiSelectIO and ImGuiSelectionRequest structures:
-    - BeginMultiSelect() and EndMultiSelect() return a ImGuiMultiSelectIO structure, which
-      is mostly an array of ImGuiSelectionRequest actions (clear, select all, set range, etc.)
-    - Other fields are helpful when using a clipper, or wanting to handle deletion nicely.
-  - Added ImGuiSelectionBasicStorage helper to store and maintain a selection (optional):
-    - This is similar to if you used e.g. a std::set<ID> to store a selection, with all the right
-      glue to honor ImGuiMultiSelectIO requests. Most applications can use that.
-  - Added ImGuiSelectionExternalStorage helper to maintain an externally stored selection (optional):
-    - Helpful to easily bind multi-selection to e.g. an array of checkboxes.
-  - Added ImGuiMultiSelectFlags options:
-    - ImGuiMultiSelectFlags_SingleSelect
-    - ImGuiMultiSelectFlags_NoSelectAll
-    - ImGuiMultiSelectFlags_NoRangeSelect
-    - ImGuiMultiSelectFlags_NoAutoSelect
-    - ImGuiMultiSelectFlags_NoAutoClear
-    - ImGuiMultiSelectFlags_NoAutoClearOnReselect (#7424)
-    - ImGuiMultiSelectFlags_BoxSelect1d
-    - ImGuiMultiSelectFlags_BoxSelect2d
-    - ImGuiMultiSelectFlags_BoxSelectNoScroll
-    - ImGuiMultiSelectFlags_ClearOnEscape
-    - ImGuiMultiSelectFlags_ClearOnClickVoid
-    - ImGuiMultiSelectFlags_ScopeWindow (default), ImGuiMultiSelectFlags_ScopeRect
-    - ImGuiMultiSelectFlags_SelectOnClick (default), ImGuiMultiSelectFlags_SelectOnClickRelease
-    - ImGuiMultiSelectFlags_NavWrapX
-  - Demo: Added "Examples->Assets Browser" demo.
-  - Demo: Added "Widgets->Selection State & Multi-Select" section, with:
-    - Multi-Select
-    - Multi-Select (with clipper)
-    - Multi-Select (with deletion)
-    - Multi-Select (dual list box) (#6648)
-    - Multi-Select (in a table)
-    - Multi-Select (checkboxes)
-    - Multi-Select (multiple scopes)
-    - Multi-Select (tiled assert browser)
-    - Multi-Select (trees) (#1861)
-    - Multi-Select (advanced)
-- Inputs: added SetItemKeyOwner(ImGuiKey key) in public API.
-  This is a simplified version of a more complete set of function available in imgui_internal.h.
-  One common use-case for this is to allow your widgets to disable standard inputs behaviors such
-  as Tab or Alt handling, Mouse Wheel scrolling, etc.
-  (#456, #2637, #2620, #2891, #3370, #3724, #4828, #5108, #5242, #5641)
-     // Hovering or activating the button will disable mouse wheel default behavior to scroll
-     InvisibleButton(...);
-     SetItemKeyOwner(ImGuiKey_MouseWheelY);
-- Nav: fixed clicking window decorations (e.g. resize borders) from losing focused item when
-  within a child window using ImGuiChildFlags_NavFlattened.
-- InputText: added '\' and '/' as word separator. (#7824, #7704) [@reduf]
-- TreeNode: added SetNextItemStorageID() to specify/override the identifier used for persisting
-  open/close storage. Useful if needing to often read/write from storage without manipulating
-  the ID stack. (#7553, #6990, #3823, #1131)
-- Selectable: added ImGuiSelectableFlags_Highlight flag to highlight items independently from
-  the hovered state. (#7820) [@rerilier]
-- Clipper: added SeekCursorForItem() function. When using ImGuiListClipper::Begin(INT_MAX) you can
-  can use the clipper without knowing the amount of items beforehand. (#1311)
-  In this situation, call ImGuiListClipper::SeekCursorForItem(items_count) at the end of your iteration
-  loop to position the layout cursor correctly. This is done automatically if provided a count to Begin().
-- Groups, Tables: fixed EndGroup() failing to correctly capture current table occupied size. (#7543)
-- Style, TabBar: added style.TabBarOverlineSize / ImGuiStyleVar_TabBarOverlineSize to manipulate
-  thickness of the horizontal line over selected tabs. [@DctrNoob]
-- Style: close button and collapse/window-menu button hover highlight made rectangular instead of round.
-- Misc: added GetID(int) variant for consistency. (#7111)
-- Debug Tools:
-  - Debug Log: Added IMGUI_DEBUG_LOG(), ImGui::DebugLog() in public API. (#5855)
-    Printed entries include imgui frame counter prefix + are redirected to ShowDebugLogWindow() and
-    other configurable locations. Always call IMGUI_DEBUG_LOG() for maximum stripping in caller code.
-  - Debug Log: Added "Configure Outputs.." button. (#5855)
-  - Debug Log: Fixed incorrect checkbox layout when partially clipped.
-- Demo: Reworked "Property Editor" demo in a manner that more resemble the tree data and
-  struct description data that a real application would want to use.
-- Backends:
-  - Backends: Win32: Fixed ImGuiMod_Super being mapped to VK_APPS instead of (VK_LWIN || VK_RWIN).
-    (#7768, #4858, #2622) [@Aemony]
-  - Backends: SDL3: Update for API changes: SDL_GetGamepads() memory ownership change. (#7807)
-  - Backends: SDL3: Update for API changes: SDL_GetClipboardText() memory ownership change. (#7801)
-  - Backends: SDL3: Update for API changes: SDLK_x renames and SDLK_KP_x removals (#7761, #7762)
-  - Backends: SDL3: Update for API changes: SDL_GetProperty() change to SDL_GetPointerProperty(). (#7794) [@wermipls]
-  - Backends: SDL2,SDL3,OSX: Update for io.SetPlatformImeDataFn() -> io.PlatformSetImeDataFn() rename.
-  - Backends: GLFW,SDL2: Added io.PlatformOpenInShellFn handler for web/Emscripten versions. (#7660)
-    [@ypujante, @ocornut]
-  - Backends: GLFW+Emscripten: Added support for GLFW3 contrib port which fixes many of the things
-    not supported by the embedded GLFW: gamepad support, mouse cursor shapes, copy to clipboard,
-    workaround for Super/Meta key, different ways of resizing, multi-window (glfw/canvas) support.
-    (#7647) [@ypujante]
-  - Backends: GLFW+Emscripten: Fixed Emscripten warning when using mouse wheel on some setups
-    "Unable to preventDefault inside passive event listener". (#7647, #7600) [@ypujante]

- VERSION 1.90.9 (Released 2024-07-01)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.9
-
-Breaking changes:
-
-- Removed old nested structure: renaming ImGuiStorage::ImGuiStoragePair type to
-  ImGuiStoragePair (simpler for many languages). No significant nested type left.
-- BeginChild: added ImGuiChildFlags_NavFlattened as a replacement for the window
-  flag ImGuiWindowFlags_NavFlattened: the feature only ever made sense for
-  BeginChild() calls anyhow. (#7687) [@cfillion]
-   - old: BeginChild("Name", size, 0, ImGuiWindowFlags_NavFlattened);
-   - new: BeginChild("Name", size, ImGuiChildFlags_NavFlattened, 0)
-  Kept inline redirection flag (will obsolete).
-- Style: renamed tab colors for clarity and consistency with other changes: (#261, #351)
-  - ImGuiCol_TabActive          -> ImGuiCol_TabSelected
-  - ImGuiCol_TabUnfocused       -> ImGuiCol_TabDimmed
-  - ImGuiCol_TabUnfocusedActive -> ImGuiCol_TabDimmedSelected
-  Kept inline redirecting enums (will obsolete).
-- IO: io.ClearInputKeys() (first exposed in 1.89.8) doesn't clear mouse data.

-- Drag and Drop: renamed ImGuiDragDropFlags_SourceAutoExpirePayload to
-  ImGuiDragDropFlags_PayloadAutoExpire. Kept inline redirecting enum (will obsolete). (#1725, #143)
-
-Other changes:
-
-- IO: do not disable io.ConfigWindowsResizeFromEdges (which allow resizing from borders
-  and lower-left corner) when ImGuiBackendFlags_HasMouseCursors is not set by backend.
-  The initial reasoning is that resizing from borders feels better when correct mouse cursor
-  shape change as honored by backends. Keeping this enabling will hopefully increase pressure
-  on third-party backends to set ImGuiBackendFlags_HasMouseCursors and honor changes of
-  ImGui::GetMouseCursor() value. (#1495)
-- IO: do not claim io.WantCaptureMouse=true on the mouse release frame of a button
-  which was pressed over void/underlying app, which is consistent/needed to allow the
-  mouse up event of a drag over void/underlying app to catch release. (#1392) [@Moka42]
-- IO: Added io.ClearInputMouse() to clear mouse state. (#4921)
-- Windows: BeginChild(): fixed a glitch when during a resize of a child window which is
-  tightly close to the boundaries of its parent (e.g. with zero WindowPadding), the child
-  position could have temporarily be moved around by erroneous padding application. (#7706)
-- TabBar, Style: added ImGuiTabBarFlags_DrawSelectedOverline option to draw an horizontal
-  line over selected tabs to increase visibility. This is used by docking.
-  Added corresponding ImGuiCol_TabSelectedOverline and ImGuiCol_TabDimmedSelectedOverline colors.
-- Tables: added TableGetHoveredColumn() to public API, as an alternative to testing for
-  'TableGetColumnFlags(column) & ImGuiTableColumnFlags_IsHovered' on each column. (#3740)
-- Disabled, Inputs: fixed using Shortcut() or SetNextItemShortcut() within a disabled block
-  bypassing the disabled state. (#7726)
-- Disabled: Reworked 1.90.8 behavior of Begin() not inheriting current BeginDisabled() state,
-  to make it that only tooltip windows are temporarily clearing it. (#211, #7640)
-- Drags: added ImGuiSliderFlags_WrapAround flag for DragInt(), DragFloat() etc. (#7749)
-- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceExtern sets
-  active id so a multi-frame extern source doesn't interfere with hovered widgets. (#143)
-- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceExtern does not assume
-  a mouse button being pressed. Facilitate implementing cross-context drag and drop. (#143)
-- Drag and Drop: Added ImGuiDragDropFlags_PayloadNoCrossContext/_PayloadNoCrossProcess flags
-  as metadata to specify that a payload may not be copied outside the context/process by
-  some logic aiming to copy payloads around.
-- Drag and Drop: Fixes an issue when elapsing payload would be based on last payload
-  frame instead of last drag source frame, which makes a difference if not resubmitting
-  payload every frame. (#143)
-- Debug Tools: Metrics/Debugger: Browsing a Storage perform hover lookup on identifier.
-- Viewports: Backported 'void* ImGuiViewport::PlatformHandle' from docking branch for
-  use by backends.

- VERSION 1.90.8 (Released 2024-06-06)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.8
-
-Breaking changes:
-
-- Reordered various ImGuiInputTextFlags values. This should NOT be breaking unless
-  you are using generated headers that have values not matching the main library.
-- Removed ImGuiButtonFlags_MouseButtonDefault_ = ImGuiButtonFlags_MouseButtonLeft
-  from imgui.h, was mostly unused and misleading.
-
-Other changes:
-
-- Inputs: fixed IsMouseClicked(..., repeat=true); broken in 1.90.7 on 2024/05/22.
-  (due to an internal api parameter swap, repeat wouldn't be honored and
-  ownership would be accidentally checked even though this api is meant to not
-  check ownership). (#7657) [@korenkonder]
-- Windows: fixed altering FramePadding mid-frame not correctly affecting logic
-  responsible for honoring io.ConfigWindowsMoveFromTitleBarOnly. (#7576, #899)
-- Scrollbar: made scrolling logic more standard: clicking above or below the
-  grab scrolls by one page, holding mouse button repeats scrolling. (#7328, #150)
-- Scrollbar: fixed miscalculation of vertical scrollbar visibility when required
-  solely by the presence of an horizontal scrollbar. (#1574)
-- InputScalar, InputInt, InputFloat: added ImGuiInputTextFlags_ParseEmptyRefVal
-  to parse an empty field as zero-value. (#7305) [@supermerill, @ocornut]
-- InputScalar, InputInt, InputFloat: added ImGuiInputTextFlags_DisplayEmptyRefVal
-  to display a zero-value as empty. (#7305) [@supermerill, @ocornut]
-- Popups: fixed an issue preventing to close a popup opened over a modal by clicking
-  over void (it required clicking over the visible part of the modal). (#7654)
-- Tables: fixed an issue where ideal size reported to parent container wouldn't
-  correctly take account of inner scrollbar, affecting potential auto-resize of
-  parent container. (#7651)
-- Tables: fixed a bug where after disabling the ScrollY flag for a table,
-  previous scrollbar width would be accounted for. (#5920)
-- Combo: simplified Combo() API uses a list clipper (due to its api it wasn't
-  previously trivial before we added clipper.IncludeItemByIndex() function).
-- Disabled: nested tooltips or other non-child window within a BeginDisabled()
-  block disable the disabled state. (#211, #7640)
-- Misc: made ImGuiDir and ImGuiSortDirection stronger-typed enums.
-- Backends: SDL3: Update for SDL_SYSTEM_CURSOR_xxx api renames. (#7653)

------------------------------------------------------------------------
- VERSION 1.90.7 (Released 2024-05-27)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.7
-
-Breaking changes:
-
-- Inputs: on macOS X, Cmd and Ctrl keys are now automatically swapped by io.AddKeyEvent(),
-  as this naturally align with how macOS X uses those keys. (#2343, #4084, #5923, #456)
-  - Effectively it means that e.g. ImGuiMod_Ctrl | ImGuiKey_C is a valid idiomatic shortcut
-    for both Windows and Mac style users.
-  - It shouldn't really affect your code unless you had explicit/custom shortcut swapping in
-    place for macOS X apps in your input logic.
-  - Removed ImGuiMod_Shortcut which was previously dynamically remapping to Ctrl or Cmd/Super.
-    It is now unnecessary to specific cross-platform idiomatic shortcuts.
-    Kept symbols redirecting ImGuiMod_Shortcut to ImGuiMod_Ctrl (will obsolete).
-- Commented out obsolete symbols renamed in 1.88 (May 2022):
-    CaptureKeyboardFromApp() -> SetNextFrameWantCaptureKeyboard()
-    CaptureMouseFromApp()    -> SetNextFrameWantCaptureMouse()
-- Backends: SDL_Renderer2/SDL_Renderer3: ImGui_ImplSDLRenderer2_RenderDrawData() and
-  ImGui_ImplSDLRenderer3_RenderDrawData() now takes a SDL_Renderer* parameter. This was previously
-  overlooked from the API but it will allow eventual support for multi-viewports.
-
-Other changes:
-
-- Windows: BeginChild(): fixed visibility of fully clipped child windows and tables to Test Engine.
-- Windows: BeginChild(): fixed auto-fit calculation when using either (not both) ResizeX/ResizeY
-  and double-clicking on a border. Calculation incorrectly didn't always account for scrollbar as
-  it assumed the other axis would also be auto-fit. (#1710)
-- Inputs: added shortcut and routing system in public API. (#456, #2637) [BETA]
-  - The general idea is that several callers may register interest in a shortcut, and only one owner gets it.
-    - in Parent: call Shortcut(Ctrl+S)    // When Parent is focused, Parent gets the shortcut.
-    - in Child1: call Shortcut(Ctrl+S)    // When Child1 is focused, Child1 gets the shortcut (Child1 overrides Parent shortcuts)
-    - in Child2: no call                  // When Child2 is focused, Parent gets the shortcut.
-    The whole system is order independent, so if Child1 makes its calls before Parent, results will be identical.
-    This is an important property as it facilitate working with foreign code or larger codebase.
-  - Added Shortcut() function:
-    e.g. Using ImGui::Shortcut(ImGuiMod_Ctrl | ImGuiKey_C); with default policy:
-    - checks that CTRL+C is pressed,
-    - and that current window is in focus stack,
-    - and that no other requests for CTRL+C have been made from higher priority locations
-      (e.g. deeper in the window/item stack).
-  - Added SetNextItemShortcut() to set a shortcut to locally or remotely press or activate
-    an item (depending on specified routing policy: using ImGuiInputFlags_RouteGlobal the item
-    shortcut may be executed even if its window is not in focus stack).
-    Items like buttons are not fully activated, in the sense that they get pressed but another
-    active item, e.g. InputText() won't be deactivated.
-  - Added routing policies for Shortcut(), SetNextItemShortcut(): (#456, #2637)
-    - ImGuiInputFlags_RouteFocused: focus stack route (default)
-    - ImGuiInputFlags_RouteActive: only route to active item
-    - ImGuiInputFlags_RouteGlobal: route globally, unless a focus route claim shame shortcut.
-    - ImGuiInputFlags_RouteAlways: no routing submission, no routing check.
-  - Added other shortcut/routing options: (#456, #2637)
-    - ImGuiInputFlags_Repeat: for use by Shortcut() and by upcoming rework of various
-      input functions (which are still internal for now).
-    - ImGuiInputFlags_Tooltip: for SetNextItemShortcut() to show a tooltip when hovering item.
-    - ImGuiInputFlags_RouteOverFocused: global route takes priority over focus route.
-    - ImGuiInputFlags_RouteOverActive: global route takes priority over active item.
-    - ImGuiInputFlags_RouteUnlessBgFocused: global route disabled if no imgui window focused.
-    - ImGuiInputFlags_RouteFromRootWindow: route evaluated from the point of view of root window rather than current window.
-- Inputs: (OSX) Fixes variety of code which inconsistently required using Ctrl instead of Cmd.
-  - e.g. Drags/Sliders now use Cmd+Click to input a value. (#4084)
-  - Some shortcuts still uses Ctrl on Mac: e.g. Ctrl+Tab to switch windows. (#4828)
-- Inputs: (OSX) Ctrl+Left Click alias as a Right click. (#2343) [@haldean, @ocornut]
-- Inputs: Fixed ImGui::GetKeyName(ImGuiKey_None) from returning "N/A" or "None" depending
-  on value of IMGUI_DISABLE_OBSOLETE_KEYIO. It always returns "None".
-- Nav: fixed holding Ctrl or gamepad L1 from not slowing down keyboard/gamepad tweak speed.
-  Broken during a refactor refactor for 1.89. Holding Shift/R1 to speed up wasn't broken.
-- Tables: fixed cell background of fully clipped row overlapping with header. (#7575, #7041) [@prabuinet]
-- Demo: Added "Inputs & Focus -> Shortcuts" section. (#456, #2637)
-- Demo: Documents: Added shortcuts and renaming tabs/documents. (#7233)
-- Examples: Win32+DX9,DX10,DX11,DX12: rework main loop to handle minimization and screen
-  locking without burning resources by running unthrottled code. (#2496, #3907, #6308, #7615)
-- Backends: all backends + demo now call IMGUI_CHECKVERSION() to verify ABI compatibility between caller
-  code and compiled version of Dear ImGui. If you get an assert it most likely mean you have a build issue,
-  read comments near the assert. (#7568)
-- Backends: Win32: undo an assert introduced in 1.90.6 which didn't allow WndProc
-  handler to be called before backend initialization. Because of how ::CreateWindow()
-  calls in WndProc this is facilitating. (#6275) [@MennoVink]
-- Backends, Examples: SDL3: updates for latest SDL3 API changes. (#7580) [@kuvaus, @ocornut]
-
-Breaking changes IF you were using imgui_internal.h versions of Shortcut() or owner-aware
-versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked() prior to this version:
-
-- Inputs (Internals): Renamed ImGuiKeyOwner_None to ImGuiKeyOwner_NoOwner, to make use more
-  explicit and reduce confusion with the fact it is a non-zero value and cannot be a default.
-- Inputs (Internals): Renamed symbols global routes:
-      Renamed ImGuiInputFlags_RouteGlobalLow  -> ImGuiInputFlags_RouteGlobal (this is the suggested global route)
-      Renamed ImGuiInputFlags_RouteGlobal     -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused
-      Renamed ImGuiInputFlags_RouteGlobalHigh -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused | ImGuiInputFlags_RouteOverActive
-- Inputs (Internals): Shortcut(), SetShortcutRouting(): swapped last two parameters order
-  in function signatures:
-      Before: Shortcut(ImGuiKeyChord key_chord, ImGuiID owner_id = 0, ImGuiInputFlags flags = 0);
-      After:  Shortcut(ImGuiKeyChord key_chord, ImGuiInputFlags flags = 0, ImGuiID owner_id = 0);
-- Inputs (Internals): owner-aware versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked():
-  swapped last two parameters order in function signatures:
-      Before: IsKeyPressed(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0);
-      After:  IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0);
-      Before: IsMouseClicked(ImGuiMouseButton button, ImGuiID owner_id, ImGuiInputFlags flags = 0);
-      After:  IsMouseClicked(ImGuiMouseButton button, ImGuiInputFlags flags, ImGuiID owner_id = 0);
-- For several reasons those changes makes sense. They were all made before making some of
-  those API public. Only past users of imgui_internal.h with the extra parameters will be affected.
-  Added asserts for valid flags in various functions to detect _some_ misuses, BUT NOT ALL.

- VERSION 1.90.6 (Released 2024-05-08)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.6
-
-Breaking changes:
-
-- TreeNode: Fixed a layout inconsistency when using a empty/hidden label followed
-  by a SameLine() call. (#7505, #282)
-     Before: TreeNode("##Hidden"); SameLine(); Text("Hello");
-             // This was actually incorrect! BUT appeared to look ok with the default style
-             // where ItemSpacing.x == FramePadding.x * 2 (it didn't look aligned otherwise).
-     After:  TreeNode("##Hidden"); SameLine(0, 0); Text("Hello");
-             // This is correct for all values in style.
-  With the fix, IF you were successfully using TreeNode("")+SameLine(); you will now
-  have extra spacing between your TreeNode and the following item. You'll need to change
-  the SameLine() call to SameLine(0,0) to remove this extraneous spacing.
-  This seemed like the more sensible fix that's not making things less consistent.
-  (Note: when using this idiom you are likely to also use ImGuiTreeNodeFlags_SpanAvailWidth).
-
-Other changes:
-
-- Windows: Changed default ClipRect to extend to windows' left and right borders,
-  instead of adding arbitrary WindowPadding.x * 0.5f space on left and right.
-  That ClipRect half-padding was arbitrary/confusing and inconsistent with Y axis.
-  It also made it harder to draw items covering whole window without pushing an
-  extended ClipRect. Some items near windows left and right edge that used to be clipped
-  may be partly more visible. (#3312, #7540, #3756, #6170, #6365)
-- Windows: Fixed subsequent Begin() append calls from setting last item information
-  for title bar, making it impossible to use IsItemHovered() on a Begin()-to-append,
-  and causing issue bypassing hover detection on collapsed windows. (#7506, #823)
-- Fonts: Fixed font ascent and descent calculation when a font hits exact integer values.
-  It is possible that some prior manual use of ImFontConfig::GlyphOffset may become
-  duplicate with this fix. (#7399, #7404) [@GamingMinds-DanielC]
-- TreeNode: Added ImGuiTreeNodeFlags_SpanTextWidth to make hitbox and highlight only
-  cover the label. (#6937) [@dimateos]
-- Tables: Angled headers: fixed multi-line label display when angle is flipped. (#6917)
-- Tables: Angled headers: added style.TableAngledHeadersTextAlign and corresponding
-  ImGuiStyleVar_TableAngledHeadersTextAlign variable. Default to horizontal center. (#6917)
-  [@thedmd, @ocornut]
-- ProgressBar: Added support for indeterminate progress bar by passing an animated
-  negative fraction, e.g. ProgressBar(-1.0f * GetTime()). (#5316, #5370, #1901)[@gan74]
-- Text, DrawList: Improved handling of long single-line wrapped text. Faster and
-  mitigate issues with reading vertex indexing limits with 16-bit indices. (#7496, #5720)
-- Backends: OpenGL3: Detect ES3 contexts on desktop based on version string,
-  to e.g. avoid calling glPolygonMode() on them. (#7447) [@afraidofdark, @ocornut]
-- Backends: OpenGL3: Update loader for Linux to support EGL/GLVND. (#7562) [@ShadowNinja, @vanfanel]
-- Backends: Vulkan: Added convenience support for Volk via IMGUI_IMPL_VULKAN_USE_VOLK define.
-  (you could always use IMGUI_IMPL_VULKAN_NO_PROTOTYPES + ImGui_ImplVulkan_LoadFunctions() as well).
-  (#6582, #4854) [@adalsteinnh, @kennyalive, @ocornut]
-- Backends: SDL3: Fixed text inputs. Re-enable calling SDL_StartTextInput()/SDL_StopTextInput()
-  as SDL3 no longer enables it by default. (#7452, #6306, #6071, #1953) [@Green-Sky]
-- Examples: GLFW+Vulkan, SDL+Vulkan: Added optional support for Volk. (#6582, #4854)
-- Examples: GLFW+WebGPU: Added support for WebGPU-native/Dawn (#7435, #7132) [@eliasdaler, @Zelif]

------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.5
-
-Breaking changes:
-
-- More formally obsoleted GetKeyIndex() when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is set.
-  It has been unnecessary and a no-op since 1.87 (it returns the same value as passed
-  when used with a 1.87+ backend using io.AddKeyEvent() function). (#4921)
-  - IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) --> IsKeyPressed(ImGuiKey_XXX)
-- ImDrawList: Merged the radius_x/radius_y parameters in AddEllipse(), AddEllipseFilled()
-  and PathEllipticalArcTo() into a single ImVec2 parameter. Exceptionally, because those
-  functions were added recently in 1.90, we are not adding inline redirection functions.
-  The transition is easy and should affect few users. (#2743, #7417) [@cfillion]
-
-Other changes:
-
-- Windows: Scrollbar visibility decision uses current size when both size and contents
-  size are submitted by API. (#7252)
-- Windows: Double-click to collapse may be disabled via key-ownership mechanism. (#7369)
-- Windows: BeginChild(): Extend outer resize borders to the edges when there are no corner
-  grips. Essentially affects resizable child windows. (#7440, #1710) [@cfillion]
-- Windows: BeginChild(): Resizing logic for child windows evaluates whether per-axis clamping
-  should be applied based on parent scrollbars, not child scrollbars. (#7440, #1710) [@cfillion]
-  Adjust those resizing limits to match window padding rather than inner clipping rectangle.
-- Tables: Fixed auto-width columns when using synced-instances of same table, width of
-  one instance would bleed into next one instead of sharing their widths. (#7218)
-- Tables: Angled headers: fixed border hit box extending beyond when used within
-  non-scrollable tables. (#7416) [@cfillion]
-- Tables: Angled headers: fixed borders not moving back up after TableAngleHeadersRow()
-  stops being called. (#7416) [@cfillion]
-- Tables: Angled headers: rounding header size to nearest integers, fixes some issues
-  when using clipper.
-- Menus, Popups: Fixed an issue where sibling menu popups re-opening in successive
-  frames would erroneously close the window. While it is technically a popup issue
-  it would generally manifest when fast moving the mouse bottom to top in a sub-menu.
-  (#7325, #7287, #7063)
-- ProgressBar: Fixed passing fraction==NaN from leading to a crash. (#7451)
-- ListBox: Fixed text-baseline offset when using SameLine()+Text() after a labeled ListBox().
-- Drags, Sliders, Inputs: Fixed io.PlatformLocaleDecimalPoint decimal point localization
-  feature not working regression from 1.90.1. (#7389, #6719, #2278) [@GamingMinds-DanielC]
-- Style: Added ImGuiStyleVar_TabBorderSize, ImGuiStyleVar_TableAngledHeadersAngle for
-  consistency. (#7411) [@cfillion]
-- DrawList: Added AddConcavePolyFilled(), PathFillConcave() concave filling. (#760) [@thedmd]
-  Note that only simple polygons (no self-intersections, no holes) are supported.
-- DrawList: Allow AddText() to accept null ranges. (#3615, 7391)
-- Docs: added more wiki links to headers of imgui.h/imgui.cpp to facilitate discovery
-  of interesting resources, because github doesn't allow Wiki to be crawled by search engines.
-  - This is the main wiki: https://github.com/ocornut/imgui/wiki
-  - This is the crawlable version: https://github-wiki-see.page/m/ocornut/imgui/wiki
-    Adding a link to the crawlable version, even though it is not intended for humans,
-    to increase its search rank.

 ### The Pitch
 
 Dear ImGui is a **bloat-free graphical user interface library for C++**. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline-enabled application. It is fast, portable, renderer agnostic, and self-contained (no external dependencies).
 
-Dear ImGui is designed to **enable fast iterations** and to **empower programmers** to create **content creation tools and visualization / debug tools** (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal and lacks certain features commonly found in more high-level libraries. Among other things, full internationalization (right-to-left text, bidirectional text, text shaping etc.) and accessibility features are not supported.

 Omar: "I first discovered the IMGUI paradigm at [Q-Games](https://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."
