It used to work just fine in 1.6, where we used an alpha8 colorspace and 
COMPOSITE_OVER to paint on selections, I'm not sure I understand why this 
would not work in 2.x. I definitely don't believe we need to double the memory 
requirements of selections to be able to paint on them: I think using a 
different composite op should be enough.
