Use symbolic constants for Render repeat modes.
Names like RepeatNone and RepeatNormal are much easier to
read and understand than bare 0 and 1.

...adds a dependency on the RepeatNone and RepeatNormal constants, which are defined in Xrender 0.10. The Xrender checks check for >= 0.6, and if you have 0.6, cairo defines it's own internal Xrender header in cairo-xlib-xrender-private.h, but for 0.8, it's in a no-man's land where it includes the headers, but doesn't define the constants.
You end up with this build failure:

simple patch to define the missing constants
Attached is a simple patch to add the defines if the Xrender version is < 0.10.
Thanks, I pushed a slightly modified patch.
