        * test/cairo-test.h: Add documentation for cairo_test functions.

        * test/cairo-test.c: (cairo_test_init), (cairo_test_expecting):
        Abstract log fie creation into cairo_test_init for use by tests
        that don't use cairo_test().

        * test/.cvsignore:
        * test/Makefile.am:
        * test/pthread-show-text.c: (start), (main): Add new test for bug
