Title:
  Weird behavior autocrop in some projections

Status in Hugin - Panorama Tools GUI:
  Fix Committed

Bug description:
  As requested in bug report 806153 a new bug report of the weird behavior of the autocrop function with some projections. Perhaps going to some extreme situations this fault comes. With normal use you don't notice and get it.
  Tested it under Windows XP 32 bits and now with Hugin 2011.4 beta1 too.

  Created the panorama and in the preview straightened and centred it.
  Following observed with the following projections

  Stereographic projection.
  Fit
  Autocrop.
  Right: 2616	Bottom: 2049
  Left : 2014	Top   :  896 
  This gives a rectangle of 602x1153=691416.

  Doing a manual crop
  Right: 2865	Bottom: 1616
  Left :   81	Top   : 1334 
  This gives a rectangle of 2784x282=785088.

  
  Panini 
  Fit -> FOV 304x102.
  Autocrop.
  Right: 2878	Bottom: 811
  Left : 1768	Top   :   0
  This gives a rectangle of 1110x811=900210.

  Doing a manual crop
  Right: 2882	Bottom: 692
  Left :   70	Top   : 122 
  This gives a rectangle of 2812x570=1532840.

  When I change the vertical FOV to 101 it crops all right, like the
  manual crop.

  Equirectangular Panini
  Fit -> FOV 304x102
  Autocrop works allright

  But when changing the vertical FOV to 109 or larger it goes wrong
  Autocrop.
  Right: 2879	Bottom: 516
  Left : 1832	Top   :   0
  This gives a rectangle of 1047x516=540252.

  Doing a manual crop
  Right: 2882	Bottom: 392
  Left :   70	Top   :  47 
  This gives a rectangle of 2812x345=970140.

  Attached is the PTO file.

  Kind regards,
  Henk Tijdink
