The following four tests are disabled:
gradient-alpha, linear-gradient, text-pattern, trap-clip
We don't use XFAIL as that would disable all backends, (but
we can still usefully use these tests on backends other than
PDF).
We update the test suite reference images where needed, (pdiff
avoided a few, but most still needed updating). We take advantage
of the need for new reference images to shrink some of the giant
tests to speed them up a bit.
This optimization provides a 2x improvement in linear gradient
generation performance (numbers from an x86 laptop):
image-rgb paint_linear_rgba_source-512 26.13 -> 11.13: 2.35x speedup

image-rgb paint_linear_rgba_source-256 6.47 -> 2.76: 2.34x speedup

image-rgba paint_linear_rgb_over-256 6.51 -> 2.86: 2.28x speedup

- 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.
New helper function to help create an image surface from a PNG file, while taking the srcdir environment variable into consideration. Rename the pattern creating helper function to match.
Use new cairo_test_create_surface_from_png so that non-srcdir builds work.
Track change in cairo_test_create_pattern_from_png.
cairo_copy cairo_get_path cairo_get_path_flat cairo_matrix_create cairo_matrix_destroy cairo_matrix_copy cairo_matrix_get_affine cairo_surface_set_repeat cairo_surface_set_matrix cairo_surface_get_matrix cairo_surface_set_filter cairo_surface_get_filter
Also, eliminate all support for compiling against, or running with old, deprecated names for functions.
Deal with all of the removals.
cairo_set_pattern -> cairo_set_source cairo_get_pattern -> cairo_get_source cairo_set_rgb_color -> cairo_set_source_rgb
-> cairo_set_source_rgba cairo_set_alpha -> cairo_get_alpha ->
Note that we'll likely want to add cairo_set_source_surface.
Add _cairo_stock_color helper function. Improve some interfaces:
_cairo_color_init _cairo_color_init_rgb _cairo_color_set_rgb -> _cairo_color_init_rgba _cairo_color_set_alpha _cairo_color_multiply_alpha
_cairo_color_get_rgb -> _cairo_color_get_rbga _cairo_color_get_rgba_premultiplied
Add cairo_stock_t and some helper macros:
CAIRO_COLOR_WHITE CAIRO_COLOR_BLACK CAIRO_COLOR_TRANSPARENT
Fix cairo_pattern_t by eliminating pattern->alpha. Fix cairo_solid_pattern_t to use cairo_color_t rather than three doubles.
Track removal of pattern->alpha, simplifying the code considerably
Track _cairo_color interface changes. Remove gstate->alpha. Propagate down set_source renamings.
cairo_pattern_add_color_stop -> cairo_pattern_add_color_stop_rgba
and add:
cairo_pattern_add_color_stop_rgb
Remove pattern->alpha, simplifying the code considerably.
Track pattern and color interface changes.
Add const where appropriate on cairo_color_t*.
Add private type inspection predicate. (cairo_xlib_surface_set_size): Add check for surface type mismatch, (no useful error reporting yet, though).
Note coverage as en expected failure.
Improve line wrap on expected failure messages.
Port all tests to new cairo_set_source interfaces.
Represent all rectangular pixel-aligned regions as regions, not just single rectangles.
Split into manageable pieces, optimize rectangular pixel- aligned regions by using _cairo_surface_fill_rectangles() or _cairo_surface_set_clip_region() as appropriate.
tests/trap-clip.c tests/trap-clip-ref.png tests/Makefile.am: Add a test for trapezoids clipping.
Add an index.
