As the path is converted to fixed-point prior to application of the
replay scale factor, we currently do anticipate some loss in precision
and slight difference in antialiasing.

PDF/PS do not have the concept of aliased rendering, so like many of the
other rasterisation tests, a1-line-width cannot be tested satisfactorily
on those backends.

In tests where we apply a scale factor to a similar source, the
recording surface will produce different results to image as the scaling
of the source is performed on the geometry and not on a raster image and
so avoids scaling artefacts.
If the environment variable ANY2PPM is set, use it as the path to the
any2ppm program. Otherwise, default to "./any2ppm" as before.
This makes it possible to set the ANY2PPM variable in the
Makefile.win32 build system, which makes it possible to use the "test"
target on the script backend.
We know have a swrast reference compositor for xlib (test-traps) and so
should not need these old xlib specific reference images.

Having discovered that I had recreated the references images with a
buggy rasteriser, we now need to recreate them with the correct reference
settings.
C99 initialization is not allowed.
Error macros are used even in the non-daemon version, hence errno.h
should always be included.
Fixes:
any2ppm.c(107) : error C2065: 'EINTR' : undeclared identifier
any2ppm.c(107) : error C2051: case expression not constant
any2ppm.c(108) : error C2065: 'EAGAIN' : undeclared identifier
any2ppm.c(108) : error C2051: case expression not constant
any2ppm.c(271) : error C2059: syntax error : '.'
MacOS X 10.7 (and maybe some previous versions, too) can fork()
processes which use CoreGraphics. This makes it possible for
cairo-test-suite to withstand a test crash without killing the whole
suite.
The old behavior is still available using the '-f' (foreground)
option.
Exercise the bug Keith found in the xlib backend, which claimed the
output from the rectangular tessellator would always be sorted.

As discussed, overloading the cairo_surface_t semantics to include
sources (i.e. read-only surfaces) was duplicating the definition of
cairo_pattern_t. So rather than introduce a new surface type with
pattern semantics, start along the thorny road of extensible pattern
types.

The output directory should be made before trying to open log files in
it.
Fixes the bug causing cairo-test-suite to log to stderr on the first
run (i.e. when test/output does not exist).
Instead of embedding the pointer in the test structure, consistently
use the cairo_test_list_t structure for test lists.
This cleans up the code as the reverse-list operation can be reused.
Moreover this makes the code clearer, because each test list is now
independent and has no way to know about other test lists.

Keep the option flags in alphabetical order. This makes it easier to
check for collisions or missing handlers.
Avoids an internal error when passing flags -c, -r or -v to
cairo-analyse-trace.
There were no tests for any subpixel order but rgb, so let's write something for
all four possibilities.
This is mostly copy&paste from test/text-antialias.c (and
text-antialias-subpixel-rgb does the same thing as text-antialias-subpixel).

This test checks if setting and unsetting mime data works correctly. E.g. this
verifies that we get the same pointer back which we passed in (=no copy made).
This test currently crashes in its last call to cairo_surface_get_mime_data().
