with a bit of OpenGL knowledge to write about 5 lines of code. :) Some of these may even be possible
w/ existing CoreImage filters.
Oliver Hunt has already made great progress with adding custom CoreImage filters to WebKit+SVG, you
can see his work as part of:
Oliver, since you had so much luck with 5192, I'm assigning this bug to you for now as I figure you
