With all of the sanitisers turned on, setting the VMA flag bits depth to 128 by default results in overly long build times. Reduce this to 64 - we can always manipulate these later for testing of larger bitmaps as needed.
Hmm, what's the problem with the sanitizers? Shouldn't this just result in slightly different codegen?
