[IDV #MPQ-882676]: Question about flow vectors from grids

Hi Tom-

Glad this works out.

Yes, for rectillinear lat/lon grids.  I'm not sure about rotated lat/lon grids.

We could always just show the true (earth relative) option and if someone wants 
the grid relative, they would have to use the formula.
