Just getting back to work after an illness... Eric's assessment is 100% correct: the transform kwarg is ignored by images. It probably could be, but it would not be trivial, particularly in the way the Agg backend is currently architected. This should probably be added as a feature request to the tracker, so we don't forget about it.
As for selective rasterization, IIRC we never really got past the API discussion. That's all that really needs to be done -- have a consistent sensical API for it -- other than that, I believe it works in PDF, PS and SVG backends already (probably not Cairo ATM, though).
