Browse Source 
* add document method to check intersection and insideness with polygon

* impl lasso selection

* impl lasso select to always add to selection

* add hint for lasso selection

* fix calculating selection mode based on direction on each pointer move

* fix lasso polygon lagging behing mouse position

* add overlay to draw lasso polygon with fill color same as quad
