[ptx] thoughts for hugin UI, post 0.5

[Bruno Postle]

Here are my thoughts on the current hugin user interface:

1. The "Images" and "Camera and Lens" tabs are the wrong way around.  

The camera attributes (type, a, b, c, fov etc..) are independent of 
anything else, in principle they can be known immediately after 
first loading the images - So they should be in the first tab where 
the images are loaded.

Whereas the roll, pitch and yaw for the photos is generally not 
known until after optimisation - This information isn't interesting 
when you start a project and should be on a later tab.

The "feature matching (autopano)" box on the first tab is unrelated 
to everything else, shouldn't it be on the "control points" tab?

2. There are settings on the last "stitcher" tab that are not really 
related to stitching and are more related to to the project itself.

The output type (and to some extent the "field of view") is critical 
to the optimisation step and often needs to be adjusted early on.

I'd like an additional "panorama" tab that contained the following:

- Pull down menu to set the panorama type.

- A small preview similar to the existing preview popup.

- "Fit" button to adjust the field of view.

- field of view boxes to set this manually.

- "centre horizontally" button (same as in the preview).

- "centre vertically" button.

- I'd quite like an interactive tool to manually pan, roll and zoom
  everything.  I currently do this by guessing values for the anchor 
  image which is awkward at best.

- The panodruid stuff from the old preview can go here.

So the preview would lose the druid and "center" and "fit" buttons 
and become a simple viewer for checking micro alignment.

The "Stitcher" tab would lose the panorama type selector and the 
"field of view" boxes, and only show stuff related to rendering and 
post-processing.
