explain why you're not doing the usual UNDEFINED to X layout transition we usually see in samples
IIRC its because the CCUDASharedMemory creates a PREINITIALIZED layout image

explain that old layout at the time of release was PREINITIALIZED and it needs to match at the time of acquire (external user of an image must put it back to same layout after done according to VK spec)
