Code review comment for lp://staging/~mc-return/compiz/compiz.merge-plugin-animationjc

I tried to investigate what exactly is the problem here, but did not find out yet.
The strange thing about this error is that composite/composite.h should exist and the other animation plug-ins use almost the same code.
Another strangeness here is the fact that it compiles as standalone plug-in (but does not work then), but does not compile when merged with lp:compiz.
