Cool, thanks for the contribution!

Good point, I fixed this in revision 212
<http://pipmak.svn.sourceforge.net/viewvc/pipmak?view=rev&revision=212>.
Your suggestion is good - wrapping the left edge of the handle into the
range [0, 360) at creation time is more efficient than checking it
modulo 360 in the hit test function.

Certainly - your change is in as revision 213 and will be included in
the next release. I made one small change (besides fixing the
indentation and adding documentation): assigning to handle.az is not
necessary in the panoramic case, Pipmak only ever uses handle.x (and
dito for el/y).

Well, yeah, but that's a bit hacky. Projects are not supposed to use
pipmak_internal (that's why it's called internal) and its contents may
change in arbitrary ways between releases, breaking your project.
