WebKit+SVG is missing support for several SVG filter elements: FE_COMPONENT_TRANSFER FE_CONVOLVE_MATRIX FE_DISPLACEMENT_MAP FE_MORPHOLOGY FE_TURBULENCE Most of these would be very easy to support by writing a small CoreImage filter, and requires someone 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: http://bugzilla.opendarwin.org/show_bug.cgi?id=5192
Oliver, since you had so much luck with 5192, I'm assigning this bug to you for now as I figure you probably have a few more filters up your sleave.
Closing this bug, as we already have individual bugs for the last missing filters.
