David, unless I'm missing something, I don't see in the spec that stitchTiles 
can be an attribute of <rect>. It should be in <feTurbulence>. According to my 
experience, if you're using x, y = 0, and width, height = 100%, you get the 
most homogeneous results with "noStitch" (FF shows an antialias line of pixels 
between rects but the stitching is fine). If you use "stitch" under the same 
conditions, only Opera gives a visually credible result. FF stiches well but 
creates a different noise pattern. Incidentally, this is very interesting 
precisely because you don't get a pattern (the line is still there 
unfortunately). Chrome repeats the pattern, like Opera, but for the stitching 
it could really use help from a tailor :)
