Closure is a fat Photoshop plug-in that renders GX Layout shapes anti-aliased (16X over-sampled). The 16x over-sampling blit-loop is entirely in the plug-in (check it out). It was written entirely during MacHack. It makes some minor modifications to the QD GX libraries and library headers so they are included her. This is not shipping quality code and should not be distributed without strong disclaimers.
