I reckon that if we imagine some typical 'usage scenarios' this will
allow us to steer the correct course between usefulness and
complexity.
On the subject of 'create_compatible_...' do we think that these will
be truly independent objects, or something akin to sub-bitmaps in the
sense that they are 'alternative representations' of the same data? In
other words, if you draw to a bitmap, will all the compatible versions
of it also change?

Makes sense.
