// 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.
// - 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 back-end in your engine/app.
// - Helper ImGui_ImplVulkanH_XXXX functions and structures are only used by this example (main.cpp) and by
// - Helper ImGui_ImplVulkanH_XXX 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.
