I believe there is a file called LoopMacros.h that defines the skeletons 
for the functions.  Then there are a number of files named after a 
particular pixel format, like "IntArgb.c", which contain a bunch of 
invocations of those macros.  Each macro invocation expands into an 
entire function.

At one point I was going to write a make target that would expand and 
format all of the files so that the actual loops could be examined, but 
that never got off the ground due to a lack of proper cross-platform 
tools...
