I'm trying to build up a revamped opengl renderer that could exploit some modern features such us fragment/vertex shader to speed up some operations.
Great! I would love to see lots of things implemented in hardware, like bezier curve interpolation, gradient rendering and so on. Unfortunately the OpenGL renderer doesn't get much attention from us due to time constraints.
I've a question about the meaning of fill style 0 and 1 when drawing paths. I've read that they are used for the left and right side of an edge, but this rule does not work on a simple swf file taken from adobe site: http://www.adobe.com/shockwave/welcome/flash.swf This contains among the other things a big red 'f' on the left and some blue boxes at the bottom. All those shapes have the same winding direction (The interior is always on the right of the edges), but the have opposite fill styles. ('f' has only fill style 1, boxes have only fill style 0)
I find coordinates difficult to visualise, but this comment from the SWF spec might help: "For shapes that don't self-intersect or overlap, FillStyle0 should be used."
