Allow user to flip X coordinate for panosphere view

[Milan Knizek]

While the "outside" view on the panosphere in GL preview shows the left and right sides correctly from mathematical view-point (considering that the camera is inside the sphere), the mirror view seems rather unnatural to me as a user.

It would be nice to add an option to flip the x coordinates so that the image is not mirrored. (I cannot say without really seeing, but I guess that keeping the "outside" view would be okay.)

I agree with the wishlist request. I feel that one should be able to directly relate the panorama preview with what is seen on the sphere in the overview, and hence the view should be from inside the sphere and be the brighter image.

I think this is still not solved, yet even more valuable if we want Hugin to have a better "visual" approach, i.e. make the Fast Panorama preview the center of a panorama workflow.

The "globe" shown in the panorama overview window looks as it is (horizontally) mirrored since the user's actual point of view is from outside the panosphere ("space ship view") looking at the surface and not from the center (the actual camera position) looking at the inside of the sphere's hull. Please consider adding an option: [x] mirror panosphere

Also please add a mouse over text for the pin icon like this:
"Click on the pin icon (or drag the Overview's title bar) to separate the docked Overview area from the Fast Panorama preview window and display a better resizeable floating window instead."

BTW compared with the usual (main) preview the "Mosaic plane" mode of the Overview doesn't seem to have more features (like shifting or turning the image) other than zooming in, at least for me on 2016.2.0 (on OS X 10.11).
