Smooth transitions between patches in mesh gradients


I finally got around to writing down an explanation of how tensor 
patches along with higher order (cubic rather than linear) colour 
interpolation can help to create smooth transitions across patch 
boundaries in mesh gradients:

This is the result of some of the discussions on this mailing list 
regarding the problem of creating smooth transitions, as well as some 
face-to-face discussions with Tav. I think it should be possible to 
integrate some these considerations in SVG 2, but if not, it might be 
good to at least highlight this particular problem for implementers, as 
then authoring tools could at least simulate similar behaviour (which, 
apparently, some tools, like Illustrator, do).
