Multiple Images, same control point

[ka9dgx]

When shooting a large panorama, it's good practice to have fairly large overlap. This means that a given point can appear in 3 or more frames. It would be helpful to be able to be able to a control point that can span all relevant frames, instead of just two of them.

This might also be very helpful in figuring out the 3d relationships between points in a panorama, and dealing with camera shift resulting from differing distance from the lens.

I have similar idea, but I think that more general and better :-)
Here is proposed workflow:
- The GUI similar or the same as in tab Control points. Left image will be panorama preview, right image arbitrary image (as now).
1. Create one (maximally two) control point by the hand for the actual panorama preview and the new image.
2. Hugin automatically aligns new image with current panorama preview by local similarity search. Partial optimization may be done - only parameters of new image will be recomputed.
3. Visual check by user, possibility to run Global optimization, add more control points for current image, etc.
4. Repeat from step 1 for all images.

Notes:
- Control point on the panorama preview will be created for all intersected images.
- Hugin needs support for local warping (or it is done by Enblend?).

Having different modes to indicate control points would be good. The exact way to implement this has not yet been fixed:

What I would suggest is less of a change I think:

If you click on a point in the preview (in "cp mode") with the control point tab selected it will (try to) add the controlpoint for all images that overlap at that point.
