Hi, I have one more suggestion you may want to try, use 'fill-opacity' instead of 'opacity'. Given the situation I suspect that this will work, and may also improve rendering performance significantly. When you use opacity it must render the fill and stroke to an offscreen image and then composite them together with the canvas using your opacity (I know in your case you don't have a stroke but it wouldn't surprise me if they didn't pick up on this optimization). When you use fill-opacity they can use the normal 'fill' code but the color it is filled with is just semi-transparent.
Oh, and yes, you really should use rasters for this (a single channel PNG used as a mask would be much better than the current arrangement). Rasters formats are _really_ good at representing lots of abutting rectangles of different colors ;) This would be even faster than the fill-opacity solution and would avoid any issues with the overlap/underlap you are seeing now. Finally I would also mention that Batik could be used to turn your svg version into a PNG (to get an 8bit PNG you would have to use the 'pallete' option of the transcoder). This might take a little bit of twiddling to get just right (you would want to match the rects with the output pixels), and using the mask element can be a little tricky (to get the coordinate systems lined up right).
