this is how the mapping pano -> image coordinates is done in panotools:

The point is always twodimensional. x,y for rectilinear images, or yaw and
pitch for equirect. images and so on.

 1. pano_proj -> erect
 2. rotate equirect?? ( rotate yaw in screenpoints ? )
 3. spherical -> erect ??
 4. persp_sphere ( rotate point with rotation
                   matrix)
 5. sphere_tp -> image_proj
 6. distortion correction
 7. shift image origin
 8. shear image

I'm not sure what steps 2 and 3 actually do, I would have to look at the
sourcecode of pano tools to figure that out. You can look at the sourcecode of
Panotools and read the rest there, though its a bit tedious to do.
