// CHANGELOG
// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
// 2025-06-11: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas. Removed ImGui_ImplSDLRenderer2_CreateFontsTexture() and ImGui_ImplSDLRenderer2_DestroyFontsTexture().
// 2025-01-18: Use endian-dependent RGBA32 texture format, to match SDL_Color.
// 2024-10-09: Expose selected render state in ImGui_ImplSDLRenderer2_RenderState, which you can access in 'void* platform_io.Renderer_RenderState' during draw callbacks.
