Comment (by strk):
Come again (sorry, but can't sleep till I succeed in getting it formatted
right)
* Will split a poly by a line, a line by a line and a line by a point
* Will always return a COLLECTION of at most 2 elements: first element is
what is left after the cut, second element is what was cut
* When you cut a line using a point, what's left is the initial portion
of the line (from start to point)
* When you cut a poly or a line using a line what's left is arbitrarly
taken as the cut-part which goes to the *left* of the cut line. This is
for assonance with the word "left"
Thanks paul if this works :)
