Weston depends on cairo and pixman, but cairo uses a special version of pixman.
In the previous commit I solved a linking problem by specifying the same pixman
version for weston, but it's easier to rely on cairo propagating it. Thanks
viric for the tip!
Also updated weston to 1.0.5, and got rid of the patch that's no longer needed.
They fixed it upstream even if it was actually caused by our pkg-config patch.
The patches fix two issues:
- screenshooter-client-protocol.h missing from tarball
- missing flags for include paths and definitions
I had to add auto* as inputs to be able to call autoreconf, as one patch
modifies a Makefile.am. Both issues are already reported upstream.
