No, we just use negative X values for front tool working. The axis and
Gremlin plus X direction was switched.

Technically, no change is really needed except to a lathe person, I
think it is more natural to think of the plus X side being toward the
tool parking side. For Gremlin, the X side features and parameters
needed to be addressed on a per feature basis.
See: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Gremlin 

I played with the Gremlin perspective view and realized (obvious really)
that the rear (and upside down) tool view is just a lathe view where Y
points away form the viewer. I haven't taken the time to figure out how
to make that view a choice yet, but may make it so that the other code
changes I made aren't needed.
