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.
We define _GNU_SOURCE globally in both the Autotools build, through the
use of the AC_USE_SYSTEM_EXTENSIONS macro; and in the Meson build, with
add_project_arguments().
It was originally added to make bisecting easier,
but has outlived its usefuleness now.
Going forward we'll have just a single cairo-version.h
header file, the one with the real version numbers.
This is needed to fix the case where cairo is being
built as a Meson subproject, but also simplifies
things in general.

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.

On AIX 6.1, getdelim() and getline() are not provided by default,
causing a gcc compilation error. With _GETDELIM defined, AIX's stdio.h
header provides definitions for these routines.

Added a new command line option FORMAT which can take rgb and/or rgba
values which enables the execution of tests only for the given FORMAT
For ex:
(1). CAIRO_TESTS="zero-alpha" make test TARGETS=ps2,image FORMAT=rgba,rgb
This command runs the zero-alpha test for both ps2 and image backends
with argb32 and rgb24 content formats.
(2). CAIRO_TESTS="zero-alpha" make test TARGETS=ps2,image FORMAT=rgba
This command runs the zero-alpha test for both ps2 and image backends
with argb32 content format and so on.

These macros are standard in src's cairoint.h and test's cairo-test.h
internal header files, so for consistency do the same thing with perf's
cairo-perf.h.

The macro benchmarks were moved to a separate repository some time ago,
but the perf README still refers to these tests as if they were still
present, which may lead to some confusion. Instead, consolodate the
macro benchmark documentation with the macro benchmarks, and focus this
README on just the (still in tree) micro-benchmarks.

If we have more rows than the max_count in any column, we end up
stretching the histogram vertically, which makes it harder to read.

If running ./cairo-perf-print in a terminal, query the terminal size and
rescale the histogram to use the maximum available space.
Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk>
If you call ./cairo-perf-print --histogram results.txt, it will then
print a histogram of the results, one per test. Ideally, you should see
a skewed distribution (with a negative skew representing that most results
run in optimal time), but random sampling errors (scheduling,
throttling, general inefficiency etc) will push it more towards a normal
distribution.

The importance of writing to the scratch surface before retrieving an

as the GetImage, in order to serialise the timer against all the

Although in this case the boolean values are guaranteed to be 1/0,
using them as true/false (in an if condition) seems much saner than
using them to limit the number of iterations on a for loop.

Keep the option flags in alphabetical order. This makes it easier to

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. :)
