See attached testcase.

This is a really simple testcase; it just sets a rotation transform and then fills a large rectangle with a solid color. The top left pixel of the canvas is well inside the interior of the rect we're filling. But somehow it (and it alone) becomes partially transparent. I discovered this bug while investigating reftest failures in bug 777194.
