// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2022-06-01: Metal: Fixed null dereference on exit inside command buffer completion handler.
// 2022-04-27: Misc: Store backend data in a per-context struct, allowing to use this backend with multiple contexts.
// 2022-01-03: Metal: Ignore ImDrawCmd where ElemCount == 0 (very rare but can technically be manufactured by user code).
// 2021-12-30: Metal: Added Metal C++ support. Enable with '#define IMGUI_IMPL_METAL_CPP' in your imconfig.h file.

- Backends: OpenGL3: Partially revert 1.86 change of using glBufferSubData(): now only done on Windows and
