Bug 1092634 - Let feColorMatrix and feComponentTransfer generate output outside their input's bounds. r=Bas

This makes the color matrix and component transfer Moz2D filters generate an infinite output, which is then cropped to the primitive's filter primitive subregion by a subsequent crop filter node. This still gives us different behavior than other browser when the primitive subregion is overridden using the x/y/width/height attributes - other browsers either ignore those completely (IE) or only let them crop the default subregion (which is defined to be the same as the input subregion) and not enlargen it - but I'll fix that in a separate bug.
