For example, to depend on cairo-script, inccairoscript was added to
"include_directories:" and libcairoscript was added to "link_with:".
This commit instead uses the libcairoscript_dep dependency everywhere.

We *always* generate this file, and we depend on its existence.
The idea behind HAVE_CONFIG_H was being able to include random files
from different projects, back in a time where "libraries" were literally
just random files instead of actual shared objects.
Since we're not in the '80s any more, and our build system(s) define
HAVE_CONFIG_H *and* generate the config.h header file, we don't need a
conditional guard around its inclusion.
Precisely what Autotools does, instead of adding it as per-target C
argument.
Once we remove HAVE_CONFIG_H checks in every source file, we'll be able
to drop it.

IGT wants to add support for planes with a bit depth >10, which
requires a higher precision format than we have currently.
I'm using RGBA as format, because of its existence in OpenGL.
With the new formats we can directly convert our bytes to half float,
or multiply a colro vector with a matrix to go to the Y'CbCr colorspace.
This requires pixman 0.36.0, so bump the version requirement.

csi-trace does not show help string correctly, due to a bug in its
command line argument parsing. strcmp returns 0 when there is an exact
match, which means it requires an inverted test.

On AIX, the token jmpbuf is a pre-processor macro.
cairo-script-scanner.c includes a private struct with a member named
jmpbuf which gets renamed to __jmpbuf when AIX's sys/context.h has been
included.
While judicious ordering of includes might kludge around this problem
(by causing all references to .jmpbuf to become .__jmpbuf), it's better
to simply select a new name for the struct member that won't suffer the
collision.

Try using the lighter-weight LZO decompressor in an effort to speed up
replays (at the cost of making the bound traces slightly larger).
Presuming that with the slight increase in file size (from -1% to +10%),
the file data remains in the readahead buffer cache, replays see a
performance improvement of between 5-10%.

The idiom (and expectation) for surface operators is that it leaves the
surface on the stack for the next operation. Also we need to hold onto a
surface reference for objects put onto the stack, yet for the

If we fail to resolve a particular pattern, try removing a few features
from the pattern and see if we can resolve that fallback and continue on
with the trace with a close approximation.
This is then behaves very similar as if the pattern requested a specific

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. :)
The existing API only described the method to be used for performing
rasterisation and unlike other API provided no opportunity for the user
to give a hint as to how to trade off performance against speed. So in
order to no be overly prescriptive, we extend the NONE/GRAY/SUBPIXEL
methods with FAST/GOOD/BEST hints and leave the backend to decide how
best to achieve those goals.

We clear past the end of the row so that we don't trigger valgrind
warning leaving harmless uninitialised bits inside the input image.
However, for RGB24 the input rowlen is 3*width, whereas we write 4*width
of data, so we need to take account of that and ensure we clear beyond
the end of the written data, not the read data.
Fixes reading of RGB24 input.

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.

During replay we want to handle recording surfaces specially, and not
redirect the creation of those to the target surface. This is similar to
the need to keep image surfaces as images during replay.

Restructure the Makefiles in .sources, .am and .win32 to enable
building cairo-script-interpreter on Win32.
Some minor changes are needed to compile on MSVC:
- include stdint.h to define INT_MAX-like macros
- redefine "inline"
- avoid deprecated functions (snprintf, replaced by _snprintf)
- define _USE_MATH_DEFINES so that math.h defines M_PI, M_SQRT2 and
M_LN2
This is a common format used by framebuffers to drive 10bpc displays
and is often hardware accelerated by XRender with underlying support
from pixman's x2r10g10b10 format (which provides coercion paths for
fallbacks).
