You're right - the Open-SWF documentation has a lot of inaccurate
statements and the parse code provided doesn't even work as expected.
Fortunately, there are couple of people working on similar stuff in the
(graphics) community and I was able to share my insights with them and so
figure out how to deal with some of the more strange descriptions from the
spec.

Luckily, this is not too hard. The technology that's needed for this dates
back at least to the 80's (e.g., use a simple scan-line renderer with an
active edge table approach, couple of lines and quadratic bezier segments,
a little forward-differencing here and there, and away you go). But today
we have the processing power to do this with neat anti-aliasing at 10
frames per second ;-)
