Yes. This is an implementation detail that should be hidden by the colour 
strategy. If all interpretation of QUANTUMS is done by the strategies, it 
makes it easier to implement things like pre-multiplied/non-pre-multiplied 
alpha, since that is just a different representation of the same pixel data.

The current code does assume RGBA in some places, but that is going to be 
replaced with colour strategy code so that we can support (at least) CMYK in 
the alpha (program alpha - not pixel alpha).
