Sample program to reproduce the rendering problem

The attached test program seems to cause Cairo to mis-render two pixels - One near the top-left and one near the bottom-right, as can be seen in the attached 32-bit PNG of the output.

The problem was noticed with cairo 1.8.6 (64-bit), using pixman 0.14.
