[Tuxpaint-devel] 2-points selection freezes when joining the 2 points

[Pere P. i C. <per...@gm...>]

Just found this: magic 2-point selection, if you let one of the points in place 
and drag the other next/over to it, Tux Paint freezes.

I've not been able to reproduce with 3-points selection.

Mended, thanks!  I glanced over the rest of the code for
slope calculations to see if any other spot might crash
due to a divide-by-zero, and didn't see any.
(Usually there's a safety check, or it's impossible for
the points to be in the same X position; this was done
for 2-Pt Persp's vanishing points, but only on _release_,
not drag!)

I've played a little with it and really enjoyed it :)
The right point escaping the left one is amazing :)
Is this the first easter egg in Tux Paint?

Hahah.  No, it's just a suboptimal and lazy solution to
the problem.  But I suppose it is kind of fun.  Just waiting
for a user to report it as a bug, 5 or 10 years from now. ;)
