* Below usage types overlap, this is intentional.
* The reason is that for Gralloc 0.3 there are very
* few usage flags we have at our disposal.
*
* The overlapping is handled by processing the definitions
* in a specific order.
*
* MALI_GRALLOC_USAGE_PRIVATE_FORMAT and MALI_GRALLOC_USAGE_NO_AFBC
* don't overlap and are processed first.
*
* MALI_GRALLOC_USAGE_YUV_CONF are only for YUV formats and clients
* using MALI_GRALLOC_USAGE_NO_AFBC must never allocate YUV formats.
* The latter is strictly enforced and allocations will fail.
*
* MALI_GRALLOC_USAGE_AFBC_PADDING is only valid if MALI_GRALLOC_USAGE_NO_AFBC
* is not present.
