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. :)

Add the cairo_time_t type (currently based on cairo_uint64_t) and use
it in cairo-observer and in the perf suite.
Fixes the build on MacOS X (for the src/ subdir) and Win32, whch
failed because they don't provide clock_gettime:
cairo-surface-observer.c:629: error: implicit declaration of function 'clock_gettime'
cairo-surface-observer.c:629: warning: nested extern declaration of 'clock_gettime'
cairo-surface-observer.c:629: error: 'CLOCK_MONOTONIC' undeclared (first use in this function)

I updated the Free Software Foundation address using the following script.
for i in $(git grep Temple | cut -d: -f1 )
do
sed -e 's/59 Temple Place[, -]* Suite 330, Boston, MA *02111-1307[, ]* USA/51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA/' -i "$i"
done

GCC uses a peculiar name for a real 128-bit integer on x86-64.
Speedups, xlib on a gm45
========================
poppler 41246.56 -> 35102.82: 1.18x speedup
swfdec-youtube 12623.01 -> 11936.79: 1.06x speedup

We refactor the surface fallbacks to convert full strokes and fills to the
intermediate polygon representation (as opposed to before where we
returned the trapezoidal representation). This allow greater flexibility
to choose how then to rasterize the polygon. Where possible we use the
local spans rasteriser for its increased performance, but still have the
option to use the tessellator instead (for example, with the current
Render protocol which does not yet have a polygon image).
In order to accommodate this, the spans interface is tweaked to accept
whole polygons instead of a path and the tessellator is tweaked for speed.
Performance Impact
==================
...
Still measuring, expecting some severe regressions.

We often use the construct:
if (_cairo_int64_lt (A, B)
return -1;
if (_cairo_int64_gt (A, B)
return 1;
return 0;
to compare two large integers (int64, or int128) which does twice the
required work on CPUs without large integer support. So replace it with a
single wideint function _cairo_int64_cmp() and therefore allow
opportunities to both shrink the code size and write a more efficient
comparison. (The primarily motivation is to simply replace each block with
a single more expressive line.)

These patches were sent to the cairo mailing list by Mathieu Lacage
<Mathieu.Lacage@sophia.inria.fr>:
http://lists.freedesktop.org/archives/cairo/2006-December/008741.html
_cairo_uint_96by64_32x64_divrem(): fixes misuse of the uint64_t type
and cairo-wideint-private.h functions.
http://lists.freedesktop.org/archives/cairo/2006-December/008742.html
Remove const qualifiers from return types from cairo-wideint.c functions.
http://lists.freedesktop.org/archives/cairo/2006-December/008747.html
Fixes a typo in cairo-wideint-private.h: _cairo_uint128_to_int128_
had an extra trailing underscore.

This patch was produced with the following (GNU) sed script:
sed -i -r -e 's/[ \t]+$//'
run on all *.[ch] files within cairo.
Note that the above script would have also created all the changes
from the previous commits to remove trailing whitespace.

Original code was of unclear provenance, this new code is completely different.

Standardize brace handling around all else clauses according to new CODING_STYLE guidelines.

(quiets the warning in gcc4). Thanks to John Ellson <ellson@research.att.com>. Closes bug #2299.

int32x32_64_mul and int64x64_128_mul are different from their unsigned compatriots

Remove cache memory usage assertions as single objects can be larger than the cache size
Decompose font matrix transformations into a couple of helper routines. Return all metrics in font space.
Eliminate compiler warning
Expect glyph metrics to be in font space. Compute text extents by fetching one glyph metric at a time, transforming to user space and computing the overall bounding box.
use 'sincos' where available. Scale factors now ensure the non-scale transform is area preserving. Scale factors requires another parameter to mark the fixed axis.
Change license to LGPL Mark int32x32_64_mul as broken (which it still is)
Ensure each glyph is located as close to the specified position as possible
interface change to _cairo_matrix_compute_scale_factors

Check status return from _cairo_gstate_glyph_extents
Quiet compiler warnings about uninitialized variables
Switch to alternate exact line intersection code.
Add 64/128-bit wide integer arithmetic.
Switch to stdint.h types (and new wide types).
