So, this is an area of active development.  Right now, you can do it
*manually* by calling the pixelizer, but unfortunately it's not automated
yet -- Anthony, JohnZ and I almost got it completely integrated to
seamlessly do this, but unfortunately work stalled for a while.  Today and
tomorrow I have to attend to some release & conference issues, but because
I think this is quite close to completion I will be putting an item on my
todo list to attempt to address this on Monday, including providing
examples and tests.

Best,

Matt
