arghh, this ifdef stuff is really, really a pain and a hack.

Please, either just drop the GLTT things or sort them out into
a new class.
I can't believe that you did it again :)

great, I have just done almost the same things yesterday :(

I would have liked to have the part_veldomain thing only and
deprecate part_velsphere, part_velcone and part_velocity.

Actuall only keeping an object called part_velocity with domain
support. THis matches closer the particle API and people can
directly use the particle documentation if they want to understand
what is going on.

Then it would be great to have domain support for the other
operations too (like part_source, etc ...)

Anyhow, good job.
