What are the features you need most? ImageCenter, optimize
presets, or the preview window? I'll work on these, starting with a
preview window that uses some function from the pano tools library to do
the stitching, so that partial stitching is possible to speed up the
preview.

If the ImageCenter window is essential, I can probably make it working
in during the next few days

There are some changes, but I think most things became simpler,
especially variable handling.

I never had the need for rotation, since I usually rotate all the
pictures (with lossless jpeg transform) into the right orientation,
before using them for anything.

almost all stuff of vigra, execpt FFT and image loading/saving is
included. The documentatoin is at its homepage, but it quite confusing
on the first look. 

Cropping shouldn't be hard to do. its just a loop that copies some
pixels and leaves out some others. But this will affect only the 
pictures in the gui, not the ones used by PTSticher. I'll have to add
this to the Panorama class as well.

ciao
