# XXX: Here are some existing tests that are currently disabled for
# one reason or another. They can still be built and run (manually)
# but we don't currently run them as part of 'make check' to avoid
# inflicting some particularly nasty problems on the user of the test
# suite (described below).
#
# It would definitely be worthwhile to address these problems so that
# these tests can get back into the test suite proper, (since the
# problems do indicated bugs somewhere and we're less likely to get
# those bugs fixed without the attention due to having these tests in
# the suite).
#
# The reasons for disabling the tests are as follows:
#
# extend-reflect - Triggers an infinite (or near-infinite) bug in some
#	X servers in some circumstances. Details and cause unknown.
#
# 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 SVG files say---so this might be
#	a useful kind of test to bring back again for performance (not
#	correctness) testing.
# text-glyph-range - This test triggers the following assertion in cairo:
#
#	lt-text-glyph-range: cairo-scaled-font-subsets.c:350:
#	_cairo_sub_font_collect: Assertion `collection->num_glyphs ==
#	collection->max_glyph + 1' failed.
#
#	And as a result causes a failure to be recorded by the test
#	suite, (in spite of the XFAIL status of the test). So maybe
#	that's just a bug in the test rig that should just consider
#	the abort an XFAIL like any other.
