// 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.
// CHANGELOG
// 2026-09-07: Round framebuffer dimensions to the nearest integer instead of truncating them. (#9538, 9515, #8628)
// 2026-04-23: Added support for standard draw callbacks (in platform_io): DrawCallback_ResetRenderState, DrawCallback_SetSamplerLinear, DrawCallback_SetSamplerNearest. Obsoleting samplers from ImGui_ImplSDLGPU3_RenderState. (#9378)
// 2026-03-19: Fixed issue in ImGui_ImplSDLGPU3_DestroyTexture() if ImTextureID_Invalid is defined to be != 0, which became the default since 2026-03-12. (#9295, #9310)
// 2026-02-25: Removed unnecessary call to SDL_WaitForGPUIdle when releasing vertex/index buffers. (#9262)
