When I tested PR2 it appeared that PostScript Level 2 forms are currently no faster than simply redrawing your image multiple times with a clip path. That is to say, they don't appear to be cached. They sure oughta be, but they aren't. Bummer. Forms would be a great way to encode multi-color sprites, if they worked. This may have changed with the final release of 3.0, but I kinda doubt it. -William Shipley The Omni Group PS: Patterns, on the other hand, are cached. They're tres fast.
