Yes that makes sense.

I have just checked code based on these suggestions.

1. Rectilinear Panorama:
   - enable yaw, if at least one horizontal control point pair
   - enable pitch, if at least one vertical control point pair
   - always enable roll if at least one vertical or horizontal ctrl. 
point pair.

2. Cylindrical + Equirect.:
   - enable roll, if 1 horiz. or vert. pair
   - enable pitch, if more than 1 horiz. or vert. pair.
