test-base basically implements rendering ala cairo-1.0 and so serves as
a useful baseline for comparing enhancements and to regression test the
core libraries.
The classic tiger's head; a simple example of a reasonably complex shape
consisting of multiple layers.

surface->use_pixmap always had the value 0. This code is taken from cairo-xlib.
However, in cairo-xlib use_pixmap is set to 20 if XGetImage() fails.

Fixes the cairo-xlib crash with tighten-bounds. (I thought I had fixed
it earlier, but I was obviously wrong.)

According to the little fishies this performs significantly better.
As a bonus, it did not handle overlapping boxes correctly...

Having spent the last dev cycle looking at how we could specialize the
compositors for various backends, we once again look for the
commonalities in order to reduce the duplication. In part this is
motivated by the idea that spans is a good interface for both the
existent GL backend and pixman, and so they deserve a dedicated
compositor. xcb/xlib target an identical rendering system and so they
should be using the same compositor, and it should be possible to run
that same compositor locally against pixman to generate reference tests.

P.S. This brings massive upheaval (read breakage) I've tried delaying in
order to fix as many things as possible but now this one patch does far,
far, far too much. Apologies in advance for breaking your favourite
backend, but trust me in that the end result will be much better. :)
File data used by a shading pattern must reusable since the pattern
may read the file multiple times. As currentfile is not reusable, use
the /ReusableStreamDecode to make it reusable.
If CAIRO_TESTS is set, argv will be replaced by a xmaloc'ed variable. We
need to free it.
This can be easily detected by running:
CAIRO_TESTS=user-font make check-valgrind TARGETS=image

When I ran "CAIRO_TESTS=a1-bug make test", no test executed because of a
bug in append_argv(). The "olen" variable was assuming that we always
only append a single argument to argv and the resulting argc was also
wrong.

Now that _emit_smask() can generate A1 masks, the _emit_imagemask()
code can be removed and emit_smask() used instead. An additional
benefit is stencil masks can be generated from ARGB32 and A8 images as
well as A1 providing that the analysis of the transparency shows that
the image is opaque or has bilevel alpha.
There are some inkscape bugs reporting very slow rendering of inkscape
generated PDFs (inkscape uses cairo for PDF output). These bugs are
caused by cairo specifying a page sized bounding box in XObjects and
Patterns. PDF renderers usually use the BBox as the image size when
compositing. As PDFs generated from SVG tends to use a lot of XObjects
and Patterns this can lead to very long rendering times.
These three patches tighten up all the BBoxes in PDF output.
"static cairo_private" means nothing and suncc complains loudly about
it. The visibility of _cairo_double_to_uint64() and
_cairo_uint64_to_double() should just be "static".
Returning a void value is an error on suncc and causes a warning on msvc:
cairo-surface-observer.c(1273) : warning C4098:
'_cairo_surface_observer_release_source_image' : 'void' function
