Finger Pointing in IDL [message #53420]

Folks,

As Mike Galloy reminded me yesterday, CONGRID does not allow
nearest neighbor re-sampling in 3D. It *always* interpolates
3D arrays.

So today I get someone complaining about TVIMAGE and the
fact that when you are displaying a 24-bit image and you
set the /NOINTERPOLATE keyword that is still interpolates
the data. Of course, I don't use CONGRID to resize the
image, I use CMCONGRID. So I am inclined to believe the
problem properly belongs to Craig and his lousy program. :-)

But, of course, the only reason I'm using CMCONGRID is
that I (used) to believe it was much better than CONGRID.

So here is my dilemma. I am now being asked to fix a problem
that is at least two programs removed from my own program.
What are my responsibilities here?

Should I fix it in my programs (lots of work), ask Craig
to fix it in his (less work, at least for me), or request
ITTVIS make CONGRID work in a manner that we would all
prefer it would work (probably less work, since they could
copy Craig's fixes for their program, and I could explain to
them how to fix my current problem)?

I thought it would be interesting to hear your opinion.

Cheers,

David
