------- Additional Comments from Stephen Chenney <schenney at chromium.org>
My opinion on this is changing yet again (thanks Simon). Canvas uses the same
code path, and a canvas test case that generates the same sequence of CG calls
(as far as I can tell) does not generate the bug.

My current theory is that this is a problem with the bounding volume. CG
definitely returns a large bound for the lone move path, which is incorrect
according to the SVG spec. If this is uses to clip the objects behind, then the
rectangle will not get drawn. Canvas definitely does not clip in this way,
which would explain why it works.
