[cairo] The short road left to 1.6 - EXTEND_PAD

Here's my contribution to 1.6. This adds 
extend_pad support to pixman (as in my previous 
patch) but also cleans up the whole 
fbfetchtransformed function that used to be 
almost 700 lines long. I broke it down in 
separate functions, and reduced some of the code duplication.

I made my own perf test in Cairo to stress this 
function and the new code should be either as 
fast or (very slightly) faster than the previous one.

This patch should be "apply and play" with 
pixman's current repository. If everything 
applies smoothly, cairo's extend-pad test should now pass.
