I've just added the changes to the current cvs.

Bruno, is the faq updated from the cvs automatically, or do we have to copy
it there by hand?

can you create screenshots with a higher jpg compression. there are so many
artefacts in these pics.

I haven't modified the , except for horizont -> horizon.

Usually I just set the image oposition for one image to yaw=180. that seems
to be enought for the optimizer, in the case I have observed problems.
But then again, the fov from the exif data I use is usually correct.

Unfortunately, no time to write a lot for the faq :(

merry xmas to you all!
