	54 On OS X, driver bugs prevent the usage of memory buffers with RGB internal

	55 format. As a workaround, the created GpuMemoryBuffer will always have

	56 internal format RGBA. The caller is responsible for handling this

	57 appropriately. The only support provided by this extension is that calls

	58 that require parameter validation (such as copyTexImage2D and

	59 copyTexSubImage2D) will perform paramter validation as if the internal

	60 format were RGB.
