Comment 2 for bug 696091

Here is a screenshot showing both the normal and quick preview for a project I was working on. I was trying to get the fence on the bottom of the image as straight as possible using the Bots parameters of Panini projection. As seen in the screenshots this parameter has a very different effect in the quick preview compared to the normal preview (Tops parameters is also showing the same behavior). The final Image is identical to the normal preview (i.e., the quick preview is wrong).

Also, I noted that this problem appears only when Bots or Tops parameters are positive (i.e., quick and normal preview are showing the same image when Tops and Bots parameters are set to 0 or to negative value).

I could reproduce the effect on two different computers and using both Hugin 2010.2.0 and 2010.4.0.
