# XXX: Here are some existing tests that are currently disabled for
# one reason or another.
# 
# show-glyphs-many - this stress test was exercising a particular bug
#      in the xlib surface code (exceeding the X11 protocol request
#      limit) when rendering several thousand glyphs at once. The
#      original xlib-surface bug is fixed now, but the test continues
#      to stress some other aspects of the test suite. For example,
#      when doing text as paths, the resuilting PostScript file is one
#      giant path that ghostscript has a particularly hard time
#      with. I'm disabling this test for now, since I don't care about
#      that performance problem in ghostscript. (But, there is a
#      similar performance problem when using cairo to rasterize the
#      equivalen giant path---from an SBG files say---so this might be
#      a useful kind of test to bring back again for performance (not
#      correctness) testing.

# All tests which have a reference image go here.
# I really don't like having to repeat this list. Anyone know a good
# way to avoid it? Can I use a wildcard here?
