// The aim of imgui_impl_vulkan.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/
// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.
// - Common ImGui_ImplVulkan_XXXX functions and structures are used to interface with imgui_impl_vulkan.cpp/.h.
// You will use those if you want to use this rendering back-end in your engine/app.
// - Helper ImGui_ImplVulkanH_XXXX functions and structures are only used by this example (main.cpp) and by
// the back-end itself (imgui_impl_vulkan.cpp), but should PROBABLY NOT be used by your own engine/app code.
// Read comments in imgui_impl_vulkan.h.
// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2019-XX-XX: *BREAKING CHANGE*: Vulkan: Added extra parameter to ImGui_ImplVulkan_RenderDrawData(). Engine/app is in charge of owning/storing 1 ImGui_ImplVulkan_FrameRenderBuffers per in-flight rendering frame. (The demo helper ImGui_ImplVulkanH_Window structure carries them.)
// 2019-XX-XX: *BREAKING CHANGE*: Vulkan: Added MinImageCount field in ImGui_ImplVulkan_InitInfo, required for initialization (was previously a hard #define IMGUI_VK_QUEUED_FRAMES 2). Added ImGui_ImplVulkan_SetSwapChainMinImageCount().
// 2019-XX-XX: Vulkan: Added VkInstance argument to ImGui_ImplVulkanH_CreateWindow() optional helper.
// 2019-04-04: Vulkan: Avoid passing negative coordinates to vkCmdSetScissor, which debug validation layers do not like.
// 2019-04-01: Vulkan: Support for 32-bit index buffer (#define ImDrawIdx unsigned int).
// 2019-02-16: Vulkan: Viewport and clipping rectangles correctly using draw_data->FramebufferScale to allow retina display.
