// Important note to the reader who wish to integrate imgui_impl_sdlgpu3.cpp/.h in their own engine/app.

|

// Calling the function is MANDATORY, otherwise the ImGui will not upload neither the vertex nor the index buffer for the GPU. See imgui_impl_sdlgpu3.cpp for more info.

// Important note to the reader who wish to integrate imgui_impl_vulkan.cpp/.h in their own engine/app.

// - Helper ImGui_ImplVulkanH_XXX functions and structures are only used by this example (main.cpp) and by
