This change makes several tests behave more like ps-eps.c, et al by
making them attempt to mkdir "output", and in case of trouble use "."
instead. filenames are now allocated at runtime due to this change, so
ensure the corresponding free()'s are in place as well.
This should facilitate running the test suite with a relative path
outside cairo's source tree, such as when employing the CAIRO_REF_DIR
environment variable.

The standard location for test output is cairo/test/output. The harness
itself was updated to write automatically generated images in this
directory, however a number of tests generate their own local output
files.
This patch updates these tests to write their output into
cairo/test/output as well, in the interest of decluttering the test
directory.

Tests should be placing output files in the output/ directory now,
although not all tests follow this standard practice. Drop the
"*.out.*" from .gitignore to make improper test behavior more evident.

This fixes a crash in the api-special-cases with xlib-xcb when calling
cairo_clip_extents() on a context that refers to a finished surface.
The crash was a simple NULL pointer dereference, because the underlying xcb
surface that was used in xlib-xcb was gone and set to NULL already.

Make cairo_push_group() fail when the context's target surface is finished.
This fixes the api-special-cases for the xcb backend:
Detected error during xcb run: error=9, seqno=0x13c, major=53, minor=0
The problem was that the Pixmap for the cairo surface was already freed and
cairo still tried to use it again as the drawable in a CreatePixmap request.

Finished surfaces and surfaces with an error status must not be usable anymore,
so refuse to work on them.
This improves the result for api-special-cases.

This adds code to the api-special-cases test which also tests the behavior of
cairo when the cairo context or the surface that is target is in an error state
or finished. These new tests call into all public entry points defined in
cairo.h which receive a cairo_t * as their first argument.
Currently this causes a new crash in the testsuite:
cairo-surface.c:394:
_cairo_surface_begin_modification: Assertion `! surface->finished' failed.

The macro benchmarks were moved to a separate repository some time ago,
but the perf README still refers to these tests as if they were still
present, which may lead to some confusion. Instead, consolodate the
macro benchmark documentation with the macro benchmarks, and focus this
README on just the (still in tree) micro-benchmarks.

When the latin subset contains glyphs that use the seac operator to
combine two glyphs, additional non winansi glyphs are added to the
subset. These extra glyphs do not have a winansi name so they can't
be renamed.
Based on a patch by Salvador Ortiz.

Even when using the stencil buffer for clipping, always scissor the clip
extents. This simplifies the code a bit.
|
|
When blitting the framebuffer during transitions to and from
multi-sampling mode, we need to disable the stencil and scissor test so
that the entire surface is preserved. This fixes the bitmap-font test
for the MSAA compositor.
|
|
When replacing the stencil buffer clip cache or destroying a surface,
destroy the cached clip. This prevents the clip from leaking.
|
|
See comments.

If subpixel rendering is enabled, but FT returns a 8bit gray bitmap
(perhaps because the font has 8bit embedded bitmaps) we were hitting
the assertions because the assumptions made were wrong. Fix up.

In some obscure conditions that I don't really understand, the image compositor
did not finish a span renderer that it created. This could then cause the last

Commit d7f5a1bec fixed a bug. This caused 12 new test failures for the
test-traps test target:
caps-tails-curve degenerate-arc degenerate-path joins subsurface
subsurface-scale twin twin-antialias-gray twin-antialias-mixed
twin-antialias-none twin-antialias-subpixel user-font
Most of these are indeed (new?) bugs. However, caps-tails-curve actually started
producing the expected result and the reference image just wrongly captures the
old state of things.
At the time of that commit, just taking the output from test-traps as the new
reference image works fine for all backends. However, with current git,
something introduced more antialiasing noise and now test-traps changed again
while cairo-xcb stayed with the old result. Thus, we also need a new reference
image to fix this test.
(The wrong reference images come from commit 8488ae02 which turned test-traps'
results into reference images)

Where a content specific reference image exists, prefer to have both
content reference images (i.e. both argb32.ref and rgb24.ref) rather
than a mix of .ref and argb32/rgb24.

These tests use reference images somewhat differently from other tests,
so treat them as special cases and avoid recommending deleting any of
their files.
Add TODO's to each test to rework them to be more consistent with other
tests.

The current sha1sum-based file checker does a blanket comparison of all
files with each other, which is fast but not directly helpful since it
doesn't distinguish between sibling files (which are allowable to be
duplicates). Also, it ignores files that may have byte differences
(such as PNG header differences) but are otherwise pixel-identical.
This patch replaces the sha1sum-based checker with one that accounts for
the default fallback path and uses perceptualdiff to compare files that
are bytewise different and verify whether they actually are different.
The intention is that the output of this command can be directly used to
remove redundant files, e.g.:
cd test
make check-ref-dups | cut -d' ' -f2 | \
while read f; do git rm "reference/$f"; done
This should have no impact on make check's results (modulo any tests
that behave erratically), and will help trim down the size of the
tarball.

cmp runs faster than perceptualdiff, and catches files that are exact
copies of the reference image. We still use perceptualdiff for catching
files that aren't bytewise identical, but are still identical at the
pixel level.

This script requires the perceptualdiff program, which can be built as
follows:
cd test/pdiff && make perceptualdiff
The script's output provides a list of target-specific or
format-specific images that are identical to their more generic
reference files, and thus are redundant and can be safely removed from
the archive without altering any test behaviors.

We can skip the intermediate evaluation of the trapezoids for
determining the extents of a stroked path by using the relatively new
functions for computing the contours of the stroke. Then we can simply
use the bbox of the points within the contours to retrieve the path
extents - which is already provided by the polygon holding the contours
of the stroke. This provides a faster result with less numerical
inaccuracy due to fewer stages required in the computation
