1. I thought at some point you were removing the word "cursor" and
starting to use "frame".
2. do these cursors contain the dimensions also?
3. CHUG*, SHEAR* etc are not defined clearly enough here. We talked about
you defining them about a year ago but you never got back to us on that,

These are rather unclear as well, as you have not properly defined cursors
and subcursors yet.

This means that the back-end has to be completely aware of any views.
I don't think that's necessarily a good thing.
