The mime surface is a user-callback surface designed for interfacing
cairo with an opaque data source. For instance, in a web browser, the
incoming page may be laid out and rendered to a recording surface before
all the image data has finished being downloaded. In this circumstance
we need to pass a place holder to cairo and to supply the image data
later upon demand.

Still hopelessly broken. Requires compiling cairo to use static linking
and then still requires manual linkage to workaround libtool. Lots of
functionality is still absent - we need to either find analogues to some
Cairo operations or implement fallbacks - but it is sufficient to
investigate how Skia functions in direct comparison with Cairo for
tessellation/rasterisation.
Caveat emptor.

Checks that coincident end-points are not converted to joins. It briefly
passed through my mind that was a good thing...

The complexity in this shape is that the stroke is reversed upon
itself and retraces the same path in the opposite direction.

As we use this a performance benchmark, it behooves us to check that we
are rendering it correctly.

A common requirement is the fast upload of pixel data. In order to
allocate the most appropriate image buffer, we need knowledge of the
destination. The most obvious example is that we could use a
shared-memory region for the image to avoid the transfer cost of
uploading the pixels to the X server. Similarly, gl, win32, quartz...
The other side of the equation is that for manual modification of a
remote surface, it would be more efficient if we can create a similar
image to reduce the transfer costs. This strategy is already followed
for the destination fallbacks and this merely exposes the same
capability for the application fallbacks.

Step 1, fix the failings sighted recently by tracking clip-boxes as an
explicit property of the clipping and of composition.

b8f43617a9 regressed the generation of
Makefiles. automake 1.10 fails when executed during ./autogen.sh:
automake: cairo_test_suite_OBJECTS should not be defined
test/Makefile.am:76: while processing program `cairo-test-suite'
A benchmark to test how close we get to reducing paint+clip to an ordinary
fill, and to check correctness.

Not sure what the right results are, so refs will come later. The output
looks superficially right, but the *code* is known to be buggy...
(And hopefully this has captured a few of those bugs.)

If I've written the tests correctly, these should produce identical
images as the a1 rasterisation tests.

ce3806510f changed the format of
Makefile.refs, breaking the check-ref-missing target.
Ignoring any line not containing a .png file fixes check-ref-missing
and makes it more robust.
Generates the lexicographical Makefile.refs based on the *.ref.png and
*.xfail.png checked into git.
This might be nice to automate as a Makefile target. But for now play
safe and do the updates manually.

The test-antialias-* tests perform the same operation with just a
different antialias flag. Sharing the code ensures that they are kept
in sync and permits adding new flags combinations easily.
Fixes https://bugs.freedesktop.org/show_bug.cgi?id=14268
The old code considered every even "word" as a key and every odd
"word" as a value when parsing a test log file.
All of the keys end with ':', so restrict with this requirement.
On linux it is impossible to check the missing references because of
argument length constraints:
make: execvp: /bin/bash: Argument list too long
Using a temporary file instead of variable expansion makes it possible
to work around this.
Makefile.refs is now required to be in lexicographical order, which
avoids ordering problems and the risk of duplicated entries (like
clipped-surface.ref.png).
