- 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.
cairoint.h: Add a helper function to take clearing areas that are outside the source/mask but are cleared by unbounded operations.
src/cairo-xlib-surface.c (_cairo_xlib_surface_composite): Use _cairo_surface_composite_fixup_unbounded() as needed.
src/cairo-image-surface.c src/cairint.h: Keep track of whether the surface has a clip or not ... we need this for determining when we can bypass an intermediate mask for composite_trapezoids().
Create an intermediate mask of the right size with pixman_add_trapezoids() and composite that.
When rendering with an unbounded operator, create the intermediate mask ourselves and render with ADD to that, then composite the result.
Create an intermediate surface the size of the extents, render the glyphs to that then composite the results.
Add the size of the glyph
Compute the size of the glyph mask, then use _cairo_surface_composite_fixup_unbounded().
Use the right mask format. (Unrelated bugfix)
New function taking a drawing function as a parameter to encapsulate shared logic between compositing trapezoid, glyphs, and masks.
Use _cairo_gstate_clip_and_composite(). Also fix extents computations for unbounded operators.
src/cairo-clip.c src/cairo-clip-private.h (_cairo_clip_combine_to_surface): Add the destination as an extra parameter to allow combining to an intermediate surface.
tests/unbounded-operator.c tests/Makefile.am: Add a test for the operation of the 6 unbounded operators against different shapes.
tests/clip-operator.c tests/Makefile.am: Add a test that tests surface clipping with different shapes against all the operators.
Make use OVER like the name and description. With fixed semantics, SOURCE does something different.
