BitRot Beaten Back

I spent a few hours this evening getting the current source base of WebKit to build as a Cairo-based project. I updated my Cairo library to 1.8, which gave the added benefit of getting the photo.svg test to work properly.

Whee!  Spinning, twirling, alpha-blending fun.

See Bug 21724 for the first set of patches.

Additional patches are still needed to get WebKit working, as there is a ton of CFNetwork, WebKitSystemInterface, and other Apple-restricted dependencies that have to be excised.
