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...

It may not be so easy to look at because it heavily uses macros.

Just for fun I would like to have a look how some routines of Java2D's
software rendering library are implemented (especially
fillprarallelogram, drawline, ...). However even after doing an
extensive search, I was not able to find the actual code implementing
those functions.
So any pointers are very welcome.
Thx
