Thanks Chris. The links give a good idea about the work going on in this area. A follow-up question - I was looking at the zoom plug-in/plug-in core in compiz 0.7.8 code (<a href="http://packages.ubuntu.com/source/intrepid/compiz">http://packages.ubuntu.com/source/intrepid/compiz</a>) and expected to find calls to the Triangle Mesh, RedirectCoordinate APIs introduced by David; but did not find any. Am I missing something here OR is the zoom plugin implemented without David's changes?
