Here are gyp targets and stubs for compiling libcc and the webkit_compositor bindings in chromium. Everything is guarded behind the off-by-default use_libcc_for_compositor gyp variable. I haven't included the actual code here, but there are scripts to sync. I plan to land + manually sync the code into place until we're ready to flip the gyp switch.
