remove support for BITMASK in vcl backends
Rather use a proper alpha channel if we need transparency.
This is another small step towards merged alpha in our vcl
layer.
I suspect the intent in a lot of this code was to save memory.
Which have been a thing way back then, but these days our
backends mostly end up doing a copy-and-convert to a real
alpha channel anyway, so the existing code is actually
now a pessimisation.
