* Doesent draw splines that are totaly out of the view (big speedup)
* Changes the spline resolution based on its size on the screen (smaller speedup)
* Draws highlighted lines ontop of unhighlighted lines, makes it easy to see where selected data links to.
* Text changes size with zoom.
* Text draws better at small sizes.
