Metal: Validate total bits used in color attachments Metal has 2 limits for color attachments. 1 the number of attachments supported. 2 the total number of bits it can write per pixel. So for example Apple4 through Apple8 GPUs can have 8 attachments but only 512bits of output. That means you can attach 8 RGBA8 textures (256bits), but you can't attach 8 RGBA32UI textures (1024bits). If there are too many bits then return FRAMEBUFFER_UNSUPPORTED from checkFramebufferStatus and INVALID_FRAMEBUFFER_OPERATION from draws Bug: angleproject:7280 Change-Id: I935aebad4d57664f59a60be20a927d6b69afb4ff Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/3674322 Reviewed-by: Kenneth Russell <kbr@chromium.org> Commit-Queue: Gregg Tavares <gman@chromium.org>
