John,

Do all the backend devices or libraries we *need* now support compound 
paths (1) at all, and (2) in a consistent enough way to solve the 
contouring problem as well as to make something like polygon collections 
more efficient?

I guess this is really part of a larger question about the degree to 
which the various graphics drawing models have converged with a rich 
intersection of capabilities, including arbitrary text rotation, precise 
text positioning, arcs, bezier curves, etc.
