Looks really nice!

One improvement would be remapping the template into the search area
projection, so that it will actually fit better. This is definately
needed for fisheye images, but wouldn't hurt for normal images as well,
especially when the points are close to the borders

I think I'll go for idea2, where there are two small magnified windows.
which can be used to correct the wrong aft point. maybe its useful to
to have a (optional) separate fine tune with a much smaller search area (a few
pixels) for these. probably I should also add a key to jump the mouse
cursor the the small window then.

We'll see if I can come up with a reliable algorithm for that.

Strange. Must be a problem with the windows version.
