[cairo] Pixman - refactoring of fbFetchTransformed - performance issue

[Antoine Azar]

I'm very surprised at this 30% number. The refactoring shouldn't come 
anywhere close to that number.

I applied Bertram's patch for the perf test suite and ran just those 
mag/min tests before and after the refactoring, and I'm seeing 1-2% 
performance differences. You can see the results of both runs and the 
speedup/slowdown factor here: http://www.antoineazar.com/refactor.htm

Could a third person run the perf before and after the refactoring to 
check the numbers?
