// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2026-04-23: Added support for standard draw callbacks (in platform_io): DrawCallback_ResetRenderState (others cannot be supported). (#9378)
// 2026-03-12: Fixed invalid assert in ImGui_ImplSDLRenderer2_UpdateTexture() if ImTextureID_Invalid is defined to be != 0, which became the default since 2026-03-12. (#9295)
// 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().
