Hold down SHIFT in the GIMP to draw straight lines with any of the tools
that draw something. Just click once to set your starting point and
then hold shift and you will see a line connecting your starting point
and your mouse. Then just click again to draw a starting line.

I was thinking it would be better to have many lines at different
angles.

Have you gone through the tutorial yet:

The image doesn't have to be anything special, just go outside
and take a picture of something with known straight lines. In
my case I just took a picture of the security bars on one of
my windows.
You can also make a grid or star burst pattern with the GIMP
and then take a picture of your screen.

To calibrate a lens Hugin wants a picture with straight
lines. Cool; I fed it one and it found two on X and one on Y.
believe it would be better to have more. I want an image of
a starburst that radiates to the edges of the paper. I spent
about half an hour looking but the webpages that had one I
liked wanted you to sign up for something. Does anyone have
something I am talking about>?
