// Missing features:
// [ ] User texture binding. Changes of ImTextureID aren't supported by this binding! See https://github.com/ocornut/imgui/pull/914
// [ ] Multi-viewport rendering (when ImGuiConfigFlags_ViewportsEnable is enabled). WORK-IN-PROGRESS.
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you use this binding you'll need to call 5 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXX_CreateFontsTexture(), ImGui_ImplXXXX_NewFrame(), ImGui_ImplXXXX_Render() and ImGui_ImplXXXX_Shutdown().

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2018-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2018-06-08: Misc: Extracted imgui_impl_vulkan.cpp/.h away from the old combined GLFW+Vulkan example.
// 2018-06-08: Vulkan: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
// 2018-03-03: Vulkan: Various refactor, created a couple of ImGui_ImplVulkanH_XXX helper that the example can use and that viewport support will use.
// 2018-03-01: Vulkan: Renamed ImGui_ImplVulkan_Init_Info to ImGui_ImplVulkan_InitInfo and fields to match more closely Vulkan terminology.
// 2018-02-18: Vulkan: Offset projection matrix and clipping rectangle by draw_data->DisplayPos (which will be non-zero for multi-viewport applications).
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback, ImGui_ImplVulkan_Render() calls ImGui_ImplVulkan_RenderDrawData() itself.
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
// 2017-05-15: Vulkan: Fix scissor offset being negative. Fix new Vulkan validation warnings. Set required depth member for buffer image copy.
