Phil is right, the pipeline is still being used
and is the fastest way to render on the framebuffers
where it is used.
As for the MITSHM ifdefs, I believe they are there
for some licensees who might want to build the
jdk w/o the MITSHM support. Although I would
not hazard to guess if it even builds w/o MITSHM
now, I haven't tried in a while.
Thanks,
Dmitri
