This just never worked too well and caused too many issues. I don't think anyone
will miss this.
As mentioned in the below bug report, proper LTO support also requires using
special versions of ranlib, nm and ar which support the LTO object files.
Otherwise, calling the normal ranlib on an .a library breaks the list of
exported symbols and thus completely breaks the static library.
This (partly) reverts the following commits:
c3645d97eb configure.ac: Add a --disable-lto configure option
d486ea30f1 configure: Conditionally include -flto
0870c6fb5b gcc-4.5 warnings and optimisation flags.
(The last commit is the one which brought us -flto in the first place even
though it doesn't talk about this. It's also the one which is only reverted
partly.)

This version removes testing code and has some changes to match my current
pixman version. My proposed pixman patch (not finished yet) will produce
exactly the same results as this cairo patch.
This code contains an all-new filter generator to replace the one that is
in pixman. Results in 222 pass/298 failed image tests, which is much better
than the previous versions of this patch.
Filter generator (which should probably be in pixman):
- Single filter, no "reconstruction" and "sample" filter
- Filters for derivative < 1 work
- Fixed IMPULSE and BOX
- Added TENT, CATMULL_ROM, NOTCH. Remove LANZCOS2.
- Renamed CUBIC to MITCHELL
Cairo's filter settings:
- CAIRO_FILTER_GOOD: uses BOX filter for scales less than .75 in either
direction. Uses PIXMAN_FILTER_GOOD (ie BILINEAR) otherwise.
- CAIRO_FILTER_BEST: uses CATMULL filter always. Upscaling more than 2x will
produce anti-aliased square pixels, similar to OS/X.
- CAIRO_FILTER_GAUSSIAN: this obsolete value is used to test other filters.
The program must declare and poke the filter into the static varialbe
ikernel. This should be removed for production code.
NYI: This version uses the fallback for xlib always. The xlib and xcb backends
must be rewritten to use the fallback version if filtering is needed. Or the
filtering code must be moved to XRender.
_cairo_int128_negate and _cairo_int128_not are #defines of
_cairo_uint128_negate and _cairo_uint128_not respectively. The function
implementations should use the actual function name not the aliases. On
systems without a uint128 type, these could lead to build issues.
Credit for finding this go to Dr. Peter Barnes, LLNL.
When --enable-qt is specified, the build will break due to missing
libstdc++:
CCLD cairo-test-suite
/usr/bin/ld: ../boilerplate/.libs/libcairoboilerplate.a(libcairoboilerplate_cxx_la-cairo-boilerplate-qt.o): undefined reference to symbol '__gxx_personality_v0@@CXXABI_1.3'
//usr/lib/x86_64-linux-gnu/libstdc++.so.6: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
When using g++ to compile and link code, g++ automatically links
libstdc++. However, in cairo we're using g++ only to compile, so need
to explicitly link against libstdc++ for backends that need iostream,
stl, or other stdc++ features.

Link-Time Optimization seems to be stable enough with gcc 4.8 and 4.9,

This reverts commit fb57ea13e0.
When running cairo-test-suite with the parameter "-a", it also runs each test
with a non-zero device-offset and device-scaling. The above commit influenced
the device-scaling results badly. E.g. some test results ended up with a black
border at the top-most and left-most row that looked like there was an offset of
"0.5" in drawing the image and thus pixels outside of the image were sampled.
This can be seen by the influence that this revert has on the results from
running CAIRO_TEST_TARGET=image ./cairo-test-suite -a:
Before: 31 Passed, 489 Failed [1 crashed, 8 expected], 31 Skipped
After: 225 Passed, 295 Failed [1 crashed, 8 expected], 31 Skipped
Most of the failures that disappeared are from the device-scaling tests.
With such disastrous results on the test suite, this cannot really be usable for
real-world applications.

These reference images are generated by the new GENERATE_REFERENCE mode that the
previous commit introduced.
I have no idea what the "base" images. From my reading of the code in
boilerplate/, these images will be used by the test-XXX targets. However, these
seem to generate the same result than e.g. the image backend. Thus, I deleted
these files.
There is still pthread-same-source.quartz.xfail.png. This file was created in
commit b6e16b8d and touched in commit 5a1e590b1. No idea if this is still valid
and since I don't have a Mac, I won't touch it.

Commit 503b6b9e2e added a check_composite method to the mask compositor, but
only added it to one of the existing implementations. This commit fixes that.
In cairo-image-compositor.c, there is already a check_composite method which
just returns success for the traps compositor. This commit makes the mask
compositor use that one.
I don't want to say much about cairo-image-mask-compositor.c except that I
wondered why this file and the file above both define a non-static function
called _cairo_image_mask_compositor_get(). In my opinion, that file should just
be deleted, since it confuses e.g. ctags, but I'll let someone else clean this
up.
