Cropping: Rotate with 'Auto crop' crops too much

[helmut]

When cropping and activating "Auto crop", the autocropping does not work quite right, the cropped area is far too large:

When cropping with 45 degrees, for example, the remaining area (square) is too small.
When cropping with -142 degrees, almost the whole image disappears.

The problem can be seen in both XnView Windows and XnView MP.

In next version of XnViewMP, i've made rewritten the function, if it's ok i'll change the routine in XnView too
