We suffer from the large overhead in calling pixman_image_composite32
per-span, but even will that overhead it is a net win with the usual
caveat about cache efficiency and function call overhead.

The actual span rasterisers may be able to specialise if they know that
the spans will be pixel aligned.

cairo_xcb_device_debug_cap_xrender_version is called by xlib-xcb's
cairo_xlib_device_debug_cap_xrender_version and thus must be marked slim_hidden.

The documentation was apparently copied from

Clearly demonstrated by using the test-base with the recording surfaces
and exemplified by the fallback-resolution with PDF, which is *almost*
fixed!
We're very close to making a release candidate for 1.12 now...

The clipping code was modified to handle partial boxes itself, so update
the base compositor to simply use the core clipping code and avoid
double application.
In order to match the reference image we need complete coverage, and the
purpose of the test is to check non-integer scaling of replays rather
than handling of the clip pixels. That partial coverage is better tested
elsewhere.

Even for a vertical edge, we still need to bias the error term otherwise
later we will find the error term is too larger and advance a pixel on
every row.

If the mask does not intersect the clip, then there is no drawing to be
performed and we can report NOTHING_TO_DO.

When estimating the maximum number of spans required for a particular
width, we need to include a closing span.

Currently you can only specify that a cairo_ft_font_face_t should
synthesize a font (to make a bold variant) through an FcPattern. That is
direct consumers of the public cairo-ft API have no control over the
synthesize options.
Rectify this by creating some public API to allow control over the
synthesis flags, and include the ability to construct an oblique as
well an embolden font.

Not 100% improvement, there are still a variety of failures with

Complete the task started in cd4b2d843b by
remembering to compute the insertion hash on the original font face as
well as the lookup hashes. Also take advantage by deferring resolution
of the implementation for the font face until after we fail to find an
already constructed scaled font.

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.

Ordinary patterns have their device offsets pre-baked into the pattern
matrix. The difference with raster patterns is that the surface is
generated upon use by the pdf,ps and so its device offset is not known
until then.

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.
I need to remember that the translation for the pattern matrix is the
inverse of the translation for drawing.

Rather than store a command to copy from a reference of another recording
surface onto this, just replay the other recording surface.

Borrow the technique for installing a proxy-snapshot developed for
acquiring the image from a recording surface.
This prevents the cairo from exploding and using up all memory due to
infinite recursion, but it does break a few tests that perform
self-copies with differing transformations.

I forgot that creating any image by defaults results in pixman
calloc'ing the pixel data and so cairo helpfully sets the is-clear flag
on the surface.

Rather than compress the copies into a clip + copy, iterate over and
perform each copy separately so as to avoid the confusion for
window-to-window copies and the solitary GC->pCompositeClip.

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.
As _cairo_surface_get_source() returns the limits of the source, a chunk
of code to query the source extents became redundant.
