cairo_get_target() returns the original surface passed to
cairo_create(), and not the current destination as required when
testing drawing to the same surface using multiple contexts.
For completeness we also use the group target when creating similar
surfaces within the tests (to check that similar surfaces of similar
surfaces also work).
- Remove cairo_test_expect_failure. cairo-test.c now checks
env var CAIRO_XFAIL_TESTS to see if the running test is
expected to fail. The reason for expected failure is
appended to the test description.
- Test description is written out.
- Failed/crashed tests also write a line out to stderr (in red),
so one can now redirect stdout to /dev/null to only see failures.
- cairo_test() has been changed to not take the draw function
anymore, instead, draw function is now part of the test struct.
- "make check" doesn't allow limiting backends to test using env
var anymore. To limit backends to test, one should use the
TARGETS variable on the make command line.
- "make check-valgrind" now writes its log to valgrind-log instead
of valgrind.log, to not interfere with test log file processing.
Change surface backend create_similar call to accept a cairo_content_t rather than a cairo_format_t.
Fix all calls into create_similar to pass a cairo_content_t rather than a cairo_format_t.
Port to use new cairo_create interface.
Rewrite all tests that were using cairo_set_target_surface to instead create a temporary cairo_t, (eventually to be replaced with cairo_begin_group).
Add a CAIRO_STATUS_BAD_NESTING error for interleaved use of two cairo_t's on the same surface. Also, add a skeleton doc comment for cairo_status_t.
src/cairo.c src/cairo-gstate.c src/cairoint.h: Use _cairo_surface_begin/end to replace _cairo_gstate_restore_external_state.
Use _cairo_surface_begin/end to save the state of a surface when we start drawing at it and restore it at the end. Check that the save level of the surface is what we expect on drawing operations and fail with CAIRO_STATUS_BAD_NESTING otherwise.
src/cairo-pattern.c src/cairoint.h (_cairo_pattern_acquire_surface_for_surface) (_cairo_pattern_release_surface): Surround use of pattern->surface with _cairo_surface->begin/end so we don't clip surfaces used as sources.
test/clip-nesting.c test/Makefile.am: Test of destinatin clipping with the nested creation of cairo_t's for the same context.
test/source-clip.c test/Makefile.am: Test that clipping on a source as a destination doesn't affect use of it as a source.
XFAIL test for copying from a surface as a source to itself as a destination with a clip.
