the horizontal and vertical line control points are not optimized to
match completely (x and y coordinates), but only in horizontal
(thus forming a vertial line) or vertical (thus forming a horizontal
line). This optimization is done in the output projection.

See some other pano tools documention for more info about this type of
control points.

Control lines (t3 and higher, in PT script speak) are not supported right
now.

have to change that.

I'm currently not using a,b,c,d,e during the preview.
Probably I should add an preview option for that. Unfortunately, I get
some artefacts when I use the pano tools function to do that.

I also can't use ptstitcher's algorithm for seaming since it appears to
be implemented in the PTStitcher binary, not the pano12 library.
