Description Aryeh Gregor (:ayg) (away until October 25) 2012-02-02 11:12:28 PST
layout/reftests/transform-3d/matrix3d-1a.html and layout/reftests/transform-3d/matrix3d-2a.html both test that a div with a particular matrix3d() transform is equivalent to another div.  But the div just contains a line of text, and the transform sends the text off the screen to the top in both cases, so it's not actually testing that they're the same.  In particular, matrix3d-2a.html is testing that "matrix3d(1,0,0,0, 0,2,0,0, 0,0,3,0, 4,5,6,1)" is equivalent to "scale3d(1,2,3) translate3d(4px,5px,6px)", but it's not -- it's equivalent to "translate3d(4px,5px,6px) scale3d(1,2,3)".

These were added in part 13 of the patchset for bug 505115.  Patch to be attached in a moment.

Reftests in this directory pass both before and after this patch.  If I undo the reversal of translate3d() and scale3d() in matrix3d-2a.html, but still add background: gold, I get a TEST-UNEXPECTED-FAIL.
