Thorsten Behrens 21ec9beae2 XCanvas does no longer imply XBitmapCanvas
Remove the implication that XCanvas IS-A XBitmapCanvas, i.e. one can
access underlying pixels. That's a preparation for display-list based
canvas implementations, and was a rather silly assumption in the first
place.

Also fixes up all client sites.
