 // (minor and older changes stripped away, please see git history for details)
-//  2024-12-09: DirectX12: Let user specifies the DepthStencilView format by setting ImGui_ImplDX12_InitInfo::DSVFormat.
-//  2024-11-15: DirectX12: *BREAKING CHANGE* Changed ImGui_ImplDX12_Init() signature to take a ImGui_ImplDX12_InitInfo struct. Legacy ImGui_ImplDX12_Init() signature is still supported (will obsolete).
-//  2024-11-15: DirectX12: *BREAKING CHANGE* User is now required to pass function pointers to allocate/free SRV Descriptors. We provide convenience legacy fields to pass a single descriptor, matching the old API, but upcoming features will want multiple.
-//  2024-10-23: DirectX12: Unmap() call specify written range. The range is informational and may be used by debug tools.
-//  2024-10-07: DirectX12: Changed default texture sampler to Clamp instead of Repeat/Wrap.
-//  2024-10-07: DirectX12: Expose selected render state in ImGui_ImplDX12_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
-//  2024-10-07: DirectX12: Compiling with '#define ImTextureID=ImU64' is unnecessary now that dear imgui defaults ImTextureID to u64 instead of void*.
 //  2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
 //  2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
 //  2021-05-19: DirectX12: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)

-//  [X] Renderer: User texture binding. Use simply cast a reference to your SDL_GPUTextureSamplerBinding to ImTextureID.
-//  [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
-
-// The aim of imgui_impl_sdlgpu3.h/.cpp is to be usable in your engine without any modification.

-// Important note to the reader who wish to integrate imgui_impl_sdlgpu3.cpp/.h in their own engine/app.

-// dear imgui: Renderer Backend for SDL_GPU
-// This needs to be used along with the SDL3 Platform Backend
-
-// Implemented features:
-//  [X] Renderer: User texture binding. Use simply cast a reference to your SDL_GPUTextureSamplerBinding to ImTextureID.
-//  [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
-
-// The aim of imgui_impl_sdlgpu3.h/.cpp is to be usable in your engine without any modification.
-// IF YOU FEEL YOU NEED TO MAKE ANY CHANGE TO THIS CODE, please share them and your feedback at https://github.com/ocornut/imgui/
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// Important note to the reader who wish to integrate imgui_impl_sdlgpu3.cpp/.h in their own engine/app.
-// - Unline other backends, the user must call the function Imgui_ImplSDLGPU_PrepareDrawData BEFORE issuing a SDL_GPURenderPass containing ImGui_ImplSDLGPU_RenderDrawData.
-//   Calling the function is MANDATORY, otherwise the ImGui will not upload neither the vertex nor the index buffer for the GPU. See imgui_impl_sdlgpu3.cpp for more info.

-Instructions to rebuild imgui_impl_sdlgpu3_shaders.h

-
-1) Compile the raw shader files to SPIRV:
-
-    glslc -o vertex.spv -c shader.vert
-    glslc -o fragment.spv -c shader.frag
-
-
-2) Build SDL_shadercross (https://github.com/libsdl-org/SDL_shadercross)
-
-
-3-A) Compiling for the Vulkan Driver:
-
-    Nothing to do, you just need the previous vertex.spv/fragment.spv, proceed to step 4
-
-
-3-B) Compiling for the DirectX 12 Driver:
-
-    ./shadercross vertex.spv -s SPIRV -d DXBC -t vertex -e main -o vertex.dxbc
-    ./shadercross fragment.spv -s SPIRV -d DXBC -t fragment -e main -o fragment.dxbc
-
-    Proceed to step 4

-3-C) Compiling for Metal (On windows you'll need the Metal Developer Tools for Windows, on linux you might use wine, but I never tested it):
-
-    ./shadercross vertex.spv -s SPIRV -d MSL -t vertex -e main -o vertex.metal

-4) Use a tool like https://notisrac.github.io/FileToCArray/ or misc/fonts/binary_to_compressed_c.cpp in imgui repository to convert the file to a uint8_t array.

 - Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame, those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder, we provide functions for popular graphics APIs (OpenGL, DirectX, etc.).
 - Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API.
  We carry the information to identify a "texture" in the ImTextureID type.

+ImTextureID is nothing more than a void*, aka 4/8 bytes worth of data: just enough to store one pointer or integer of your choice.
 Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely passes ImTextureID values until they reach your rendering function.
 - In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) backends, for each graphics API we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using:
 ```cpp
 OpenGL:

-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// Important note to the reader who wish to integrate imgui_impl_sdlgpu3.cpp/.h in their own engine/app.
-// - Unline other backends, the user must call the function Imgui_ImplSDLGPU_PrepareDrawData BEFORE issuing a SDL_GPURenderPass containing ImGui_ImplSDLGPU_RenderDrawData.
-//   Calling the function is MANDATORY, otherwise the ImGui will not upload neither the vertex nor the index buffer for the GPU. See imgui_impl_sdlgpu3.cpp for more info.

-//   You will use those if you want to use this rendering backend in your engine/app.
-// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by

-
-// Learn about Dear ImGui:
-// - FAQ                  https://dearimgui.com/faq
-// - Getting Started      https://dearimgui.com/getting-started
-// - Documentation        https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
-// - Common ImGui_ImplVulkan_XXX functions and structures are used to interface with imgui_impl_vulkan.cpp/.h.
-//   You will use those if you want to use this rendering backend in your engine/app.
-// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by
-//   the backend itself (imgui_impl_vulkan.cpp), but should PROBABLY NOT be used by your own engine/app code.
-// Read comments in imgui_impl_vulkan.h.
