Calculating boundingboxes implies interpreting the actual curves,
and that eats up lots of memory. I'll see if I can create a shortcut
somewhere. If I don't have to calculate boxes afterward, then there
is no need to interpret and save the curves, and the resulting memory
footprint should be much lower.

Best wishes,
