[cairo] get-clip-svg-* test failures

[Bryce Harrington]

Starting a few days ago, we've been seeing some new test fails:

get-clip-svg-argb32 [0]: FAIL
get-clip-svg-argb32 [25]:       FAIL
get-clip-svg-rgb24 [0]:         FAIL
get-clip-svg-rgb24 [25]:        FAIL

Also, I've noticed a number of 'Failed to open display:' warnings; I
have xorg installed on the test machines but not actually running.  Does
the testsuite require X be up?

Thanks,
Bryce
