That looks great. We should definitely just re-generate the reference image. ;-)

Because "-k" means "keyword" and these are not related to the name of the test.
For example in test/record-neg-extents.c:

CAIRO_TEST (record_neg_extents_unbounded,
	    "Paint unbounded recording pattern with untransformed extents outside of
target extents",
	    "record,transform,pattern", /* keywords */
	    NULL, /* requirements */
	    WIDTH, HEIGHT,
	    NULL, record_neg_extents_unbounded)

The first argument is the name of the test and the third argument is the list of
keywords.

If you just want to run a test directly, get rid of the -k:

$ DISPLAY=:5 CAIRO_TEST_TARGET=xlib ./cairo-test-suite record-neg-extents
