radiating lines from central point

[Brian Cluff]

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.
