untested cairo patch.

Initial Package Version: 1.4.14
Upstream Status: Not offered, would be rejected as bogus
Origin: Self - revert one line of the 1.4.14 changes
Description: Possible fix for https://bugzilla.mozilla.org/show_bug.cgi?id=413583
(render bug, e.g. on certain png images).  Before version 1.4.14, the test always
enabled the workaround for buggy repeat with recent xorg because they had reset
the version number to 1.  Among other things, the wrokaround slows down the
rendering.

The bug has been reported by users of ati-6.7.19x video, sis 0.9.3, i810.  The
common factor seems to be that all the reporters were using xorg-server-1.3.0.0 -
that was shipped by e.g. fedora, ubuntu but wasn't the released version for 7.2
or 7.3.  For myself, I cannot replicate it with ati-6.7.196 on server 1.4.0.90,
and that driver does not build for server 1.2.0 which was the 7.2 version.

Totally untested.
