Improved unzoom, partial images dimensions from command line

[nobody]

Dear panoglview developers,

  when using the wonderful panoglviewer, I met with some of its features which I found a little disturbing. So I have tried to create a patch for panoglview that:

1) Improves unzooming procedure in the case view boundaries are defined: the present behavior is that when unzooming the panorama near the boundaries, then the unzooming stops as soon as any of top, bottom, left or right boundary is reached. The patch allows further unzooming by moving also the center position of the view (of course until the view fits in the given boundaries).

2) Support for partial images from command-line: an optional second cmd-line parameter defines the pan-width of the image (tilt-height is recalculated from the image dimensions).

3) Initial desktop file to be placed in /usr/share/applications by default

If you would find out any of the changes useful, feel free to pick it up. The full patch (w.r.t. panoglview-0.2.2) is attached.
Best regards,
Pavel
