[Pixman] [PATCH 0/3] Two new demo programs

[Søren Sandmann]

The following patches add two new demo programs:

- quad2quad, which will compute the projective transformation that
  maps one quadrilateral into another

- checkerboard, which shows a checkerboard being projectively
  transformed.

There is nothing earthshattering about either one, but they might as
well go into pixman master as sit in my repository.
