Promote RGBA4444 and RGB565 to RGB[A]8 on macOS with AMD GPUs. There are bugs in Apple's OpenGL driver when uploading to textures of these formats via pixel buffer objects. Because automatic graphics switching might activate the AMD GPU at any time, use this workaround on dual-GPU MacBook Pros even if the Intel GPU is active. Fixes the following WebGL 2.0 conformance tests: deqp/functional/gles3/texturespecification/ teximage2d_pbo_2d_00.html teximage2d_pbo_2d_01.html texsubimage2d_pbo_2d_00.html texsubimage2d_pbo_2d_01.html texsubimage2d_pbo_cube_01.html Bug: angleproject:5469 Change-Id: I7d65dc5f664159b4b59d46400a8d9c492f67040b Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/2595245 Commit-Queue: Kenneth Russell <kbr@chromium.org> Reviewed-by: Jonah Ryan-Davis <jonahr@google.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>
