-----------
New grease pencil mode: poly line drawing
- It's like sketch mode for lines, but you're specifying line knots
by clicking on position you want to add next knot.
- View can be navigated between knots creation.
- Holding LMB down and sliding mouse will lead to new segment preview
so it can be created more accurate.
Additional change: fixed GP->Bezier conversion. Last point used to
be ignored in this operator.
