[cairo] xcb is passing, xlib? Re: What does it take to get a make check to pass with the xcb target, using CAIRO_REF_DIR?

Yay, xcb target passes (at least with regenerated references):
https://bugs.freedesktop.org/show_bug.cgi?id=84330

image16 and image also appear to be passing.

The one I'm most curious about now is xlib:

   1062 xlib PASS
      4 xlib FAIL
      2 xlib XFAIL

$ cat *.log | grep ^TEST: | grep 'xlib ' | grep ' FAIL'
TEST: record-neg-extents-bounded TARGET: xlib FORMAT: argb32 OFFSET: 0 SCALE: 1 SIMILAR: 0 RESULT: FAIL
TEST: record-neg-extents-bounded TARGET: xlib FORMAT: rgb24 OFFSET: 0 SCALE: 1 SIMILAR: 0 RESULT: FAIL
TEST: record-neg-extents-unbounded TARGET: xlib FORMAT: argb32 OFFSET: 0 SCALE: 1 SIMILAR: 0 RESULT: FAIL
TEST: record-neg-extents-unbounded TARGET: xlib FORMAT: rgb24 OFFSET: 0 SCALE: 1 SIMILAR: 0 RESULT: FAIL

Yup, something pretty wrong is happening there.
