grey lines in canvas demo http://tulrich.com/geekstuff/canvas/perspective.html Note that the demo is super slow due to bug 28692. I'm not sure if these lines are from anti-aliasing or what. These lines do not appear in Chroimium Win and Chromium Linux, but they do in Safari Mac and Chromium Safari. I'm told these images have a clipping path, and that we're "not supposed to antialias along the clipping path". I'm not enough of a graphics expert to know what proper behavior here is, but our behavior is at least different. CCing oliver due to his historical interest in this type of bug.
