I'd want to be able to stick bitmap images onto canvases with
transparency. e.g. take this PNG which has a transparent
border, and display it with alpha=0.5 (meaning the transparent
border would remain with alpha=0, but the body of the image
would have alpha=0.5 and be translucent).

Does this sort of thing fit with either model?
