VMU format is 12-bit RGB. Truncating to 8-bit and using the existing read_region API is good enough for now, but we might want to give access to the higher-depth data in some way.

The correct solution is to add ARGB64 support to cairo and pixman, then to either add a new API call to openslide, or just expose this through openslide_cairo_read_region.

That is a big amount of work though. Try to do it that way, please!
