// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2026-XX-XX: DirectX10: Added support for ImDrawCallback_SetSamplerLinear, ImDrawCallback_SetSamplerPoint.
// 2026-01-19: DirectX10: Added 'SamplerNearest' in ImGui_ImplDX10_RenderState. Renamed 'SamplerDefault' to 'SamplerLinear'.
// 2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
// 2025-06-11: DirectX10: Added support for ImGuiBackendFlags_RendererHasTextures, for dynamic font atlas.
