Now that the END snap works for lines and line strips it's time to plan how to do INT snaps.

A naive approach to the problem would be to traverse all line-like entities, test for intersection and then test the results for distance to the click. With adecuate caching it may be feasible.

Well, I had a bit of fun testing the diary :)

I decided to make a call similar to cadget.clicks() called cadget.snaps() that returns a tuple [[xyz][xyz][xyz]] of the already snapped clicks. The clicks queue remains untouched.

Boring stuff today. I have commited the code to do vertex snaps in Fandango, but it still needs tweaks. It only finds a snap at a time. That complicates matters when drawing individual lines and having to snap both ends. I think that I'll do a parallel stack to iWindow::getClickQueue() that will return the snapped or clicked vertex instead of clicks only.
