[Papervision3D] AS3 drawing API - filled 2x slower then wireframe

[Philippe Ajoux]

Tim,

I know you have some experience with this, but I just wanted to give my
personal account input:

If you raster your own stuff using setPixels() and such you probably will
outperform Flash when it comes to
solid fills or even other color fills. However, once you have to do
texturing, which requires a getPixel() (from the
texture) Flash will outperform AS rastering. Plus the screen size must be
limited. However, this is just my experience.
If someone finds a way around this, please inform me, for that would be
stupendous.
