+// dear imgui: Renderer Backend for Vulkan
+// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
+
+// Implemented features:
+//  [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
+// Missing features:
+//  [ ] Renderer: User texture binding. Changes of ImTextureID aren't supported by this backend! See https://github.com/ocornut/imgui/pull/914
+
+// 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.
+// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
+// Read online: https://github.com/ocornut/imgui/tree/master/docs
+
+// 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_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.

+// [Configuration] in order to use a custom Vulkan function loader:
+// (1) You'll need to disable default Vulkan function prototypes.
+//     We provide a '#define IMGUI_IMPL_VULKAN_NO_PROTOTYPES' convenience configuration flag.
+//     In order to make sure this is visible from the imgui_impl_vulkan.cpp compilation unit:
+//     - Add '#define IMGUI_IMPL_VULKAN_NO_PROTOTYPES' in your imconfig.h file
+//     - Or as a compilation flag in your build system
+//     - Or uncomment here (not recommended because you'd be modifying imgui sources!)
+//     - Do not simply add it in a .cpp file!
+// (2) Call ImGui_ImplVulkan_LoadFunctions() before ImGui_ImplVulkan_Init() with your custom function.
+// If you have no idea what this is, leave it alone!

+// You may read this code to learn about Vulkan, but it is recommended you use you own custom tailored code to do equivalent work.
