  Message : Add EGL_ANGLE_device_cgl extension. Supports querying the CGLContextObj and CGLPixelFormatObj associated with ANGLE's underlying OpenGL context on macOS. Minor refactorings to implementation of device attribute queries on all platforms. Bug: angleproject:3973 Change-Id: I24341668be4cbfed0b7f2df4c1402df1effe275e Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/1846733 Commit-Queue: Kenneth Russell <kbr@chromium.org> Reviewed-by: Jamie Madill <jmadill@chromium.org>
