// dear imgui: Platform Backend for GLUT/FreeGLUT
// This needs to be used along with a Renderer (e.g. OpenGL2)
// !!! GLUT/FreeGLUT IS OBSOLETE PREHISTORIC SOFTWARE. Using GLUT is not recommended unless you really miss the 90's. !!!
// !!! If someone or something is teaching you GLUT today, you are being abused. Please show some resistance. !!!
// !!! Nowadays, prefer using GLFW or SDL instead!
// Implemented features:
// [X] Platform: Partial keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLUT values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
// Issues:
// [ ] Platform: GLUT is unable to distinguish e.g. Backspace from CTRL+H or TAB from CTRL+I
// [ ] Platform: Missing horizontal mouse wheel support.
// [ ] Platform: Missing mouse cursor shape/visibility support.
// [ ] Platform: Missing clipboard support (not supported by Glut).
// [ ] Platform: Missing gamepad support.
// 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
// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2023-04-17: BREAKING: Removed call to ImGui::NewFrame() from ImGui_ImplGLUT_NewFrame(). Needs to be called from the main application loop, like with every other backends.
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
// 2019-04-03: Misc: Renamed imgui_impl_freeglut.cpp/.h to imgui_impl_glut.cpp/.h.
// 2019-03-25: Misc: Made io.DeltaTime always above zero.
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
// 2018-03-22: Added GLUT Platform binding.
