GPU: Add fallback when 16-bit formats are not supported (#4108)
* Add conversion for 16 bit RGBA formats (not supported in Rosetta) * Rebase fix Rebase fix * Forgot to remove this * Fix RGBA16 format conversion * Add RGBA4 -> RGBA8 conversion * Handle host stride alignment * Address Feedback Part 1 * Can't count * Don't zero out rgb when alpha is 0 * Separate RGBA4 and 5-bit component formats Not sure of a better way to name them... * Add A1B5G5R5 conversion * Put this in the right place. * Make format naming consistent for capabilities * Change method names
