One thing that might be worth trying if this is a real problem for 
you -- but it will require some programming -- is to make use of the
start_rasterizing and stop_rasterizing methods of MixedModeRenderer. 
You would have to create your own artist class or modify one of the 
existing artists to call start_rasterizing before the expensive part and
stop_rasterizing afterwards, so that the expensive part becomes a bitmap
image in the pdf file.

I think quad meshes used to do this, but I don't see any calls to
start_rasterizing in the current code. Perhaps there was some difficulty
with this approach.
