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.
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.

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).

Exercise the case of stroking a box with a pen wider than the box
itself, a variation on line-width-overlap suggested by Paulo Zanoni.

The recording surface has no knowledge of the target surface when it
generates the scaled font and informs the client about the kerning and
metrics. This results in an unfortunate slight misalignment when
replaying the glyphs against the ideal case.

Poppler renders the PDF output of this test correctly with cairo 1.10.2 but fails with current git.
Commenting out the cairo_translate makes the PDF output render correctly with current git.
Debate rages as to the correct way to handle this. In some ways the
current output is expected due to the numerical instability in handling
the inner-focus-on-the-outer-circle. However, the result looks less than
desirable so some solution (which may not be inside cairo per-se) is
sought.
Uli Schlachter spotted that I had create reference images with sharp
edges for his tighten-bounds test case, exactly as if I had ignored
unaligned clip boxes...
Turns out I had removed the code to handle them...
The test-traps provides a reference implementation of the
traps-compositor as used by xlib, so we can use it to generate the
reference images as well. (Of course checking that test-traps is itself
correct and only differs in the renderer! ;-)

With over two thousand references images now, it is starting to make the
test directory look cluttered!
