Yes, that's an obvious and unpleasant limitation: Something that should 
behave as transparent (cut-out of another object) is mimicked by a 
hardcoded white area.

I'm not sure this can be remedied easily. I don't understand much of the 
output code, but my impression is that filled-rounded-boxes are created 
by using corresponding features of the respective output engine (PS 
interpreters, SVG standard, Cairo). I may be wrong, but this would seem 
to indicate that, for an actual solution, one would either need actual 
nonfilled-rounded-box support in all these engines, or instead a way to 
remove parts of an already drawn stencil.

But I'm happy to be corrected by those who understand the workings of 
the output engines.
