Hrm. A general mechanism for getting a caching canvas for a given
canvas would be nice. For instance, you might have an 8-bit display,
but drawOn: might be given a PostscriptCanvas as an argument--you'd like
to cache in full color rather than 8-bit color (assuming Squeak's
PostscriptCanvas handles color).
It would be nice to have "aCanvas canvasForCaching: size".
