65919ad17f Ensure that tests run as the last step of a build for 'make check' 
Previously 'make check' would compile and run tests first, and only
then proceed to compiling demos. Which is not very convenient
because of the need to scroll back console output to see the
tests verdict. Swapping order of SUBDIRS variable entries in
Makefile.am resolves this.

there is no reason to mark the image dirty and incur a recomputation
of the flags.

3598ec26ec Add new public function pixman_add_triangles() 
This allows some more code to be deleted from the X server. The
implementation consists of converting to trapezoids, and is shared
with pixman_composite_triangles().

964c7e7cd2 Optimize adding opaque trapezoids onto a8 destination. 
When the source is opaque and the destination is alpha only, we can
avoid the temporary mask and just add the trapezoids directly.

79e69aac8c Add support for triangles to pixman. 
The Render X extension can draw triangles as well as trapezoids, but
the implementation has always converted them to trapezoids. This patch
moves the X server's triangle conversion code into pixman, where we
can reuse the pixman_composite_trapezoid() code.

4e6dd4928d Add a test program for pixman_composite_trapezoids().

actually works.

803272e38c Add pixman_composite_trapezoids(). 
This function is an implementation of the X server request
Trapezoids. That request is what the X backend of cairo is using all
the time; by moving it into pixman we can hopefully make it faster.

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).

8e4100260b SSE2 optimization for nearest scaled over_8888_n_8888

b099957887 Better support for NONE repeat in nearest scaling main loop template 
Scaling function now gets an extra boolean argument, which is set
to TRUE when we are fetching padding pixels for NONE repeat. This
allows to make a decision whether to interpret alpha as 0xFF or 0x00
for such pixels when working with formats which don't have alpha
channel (for example x8r8g8b8 and r5g6b5).

14f82083a1 Support for a8 and solid mask in nearest scaling main loop template 
In addition to the most common case of not having any mask at all, two
variants of scaling with mask show up in cairo traces:
1. non-scaled a8 mask with SAMPLES_COVER_CLIP flag
2. solid mask

This patch extends the nearest scaling main loop template to also
support these cases.

e83cee5aac test: Extend scaling-test to support a8/solid mask and ADD operation 
Image width also has been increased because SIMD optimizations typically
do more unrolling in the inner loops, and this needs to be tested.

8d359b00c5 C fast paths for a simple 90/270 degrees rotation 
Depending on CPU architecture, performance is in the range of 1.5 to 4 times
slower than simple nonrotated copy (which would be an ideal case, perfectly
utilizing memory bandwidth), but still is more than 7 times faster if
compared to general path.

This implementation sets a performance baseline for rotation. The use
of SIMD instructions may further improve memory bandwidth utilization.
