We don't have immediate plans to implement general polygons, but that's
certainly a possibility. The biggest issue is agreeing on fixed vs.
precision, what to do with slicing, whether to introduce triangle and/or
as primitives, etc. The current data abstraction, isotropy, scan-lines
would all hold.
