Hello Sandro,

For everything that's not a Glyph. There is no distinction between
dynamic and SWF-defined shapes.

SWF-defined shapes use the even-odd filling rule and the proprietary
player apparently uses that for dynamic shapes, too. So it would be
incorrect to distinguish them.

However, AGG still manages to render the shape correctly. I guess this
depends on it's particular implementation. Once I understand that, I
can re-implement it in the point test algorithm. A discussion about
this is going on in the AGG mailing list.
