460faaa411 demos: Add linear-gradient demo program 
This program displays a linear gradient from blue to yellow. Due to
limited precision in pixman-gradient-walker.c, it currently has some
ugly artefacts that gives it a 'brushed metal' appearance.

V2: Update .gitignore

61dacffaf4 Convert INCLUDES to AM_CPPFLAGS 
INCLUDES has been deprecated starting with automake 1.13. Convert all
occurrences with the recommended AM_CPPFLAGS replacement.

4f18ba30ce Add demo program for conical gradients 
This new test is derived from radial-test.c and displays conical
gradients at various angles.

It also demonstrates how PIXMAN_REPEAT_NORMAL is supposed to work when
used with a gradient specification where the first stop is not a 0.0:
In this case the gradient is supposed to have a smooth transition from
the last stop back to the first stop with no sharp transitions. It
also shows that the repeat mode is not ignored for conical gradients
as one might be tempted to think.

97491ed26c demos: Add new demo program, "scale" 
This program allows interactively scaling and rotating images with
using various filters and repeat modes. It uses
pixman_filter_create_separate_convolution() to generate the filters.

b31a696263 test: Switch to the new PRNG instead of old LCG 
Wallclock time for running pixman "make check" (compile time not included):

But some tests got a particularly large boost. For example benchmarking and

09cb1ae10b demos: Add srgb_trap_test.c 
This demo program composites a bunch of trapezoids side by side with
and without gamma aware compositing.

a161a6ba23 Add sRGB blending demo program 
Simple sRGB color blender test can be used to determine if the sRGB processing
works as expected. It blends alpha ramps of purple and green together such that
at midpoint of image, 50 % blend of both is realized. At that point, sRGB-aware
processing yields a result close to #bbb rather than #888, which is the linear
light blending result.

The demo also contains the sample computation for sRGB premultiplied alpha.

100f16eae9 tests: Add PNG_CFLAGS/LIBS to tests 
PNG flags were accidentally included by gdk-pixbuf. This has been fixed
recently, so we need to make sure to include it ourselves.

7dfe845786 Move all the GTK+ based test programs to a new subdir, "demos" 
This separates the test suite from the random gtk+ using test
programs. "demos" is somewhat misleading because the programs there
are not particularly exciting (with the possible exception of
composite-test which shows off all the compositing operators).
