Compute the projection along given directions of surface element edges onto target edges.

Parameters

corners1	The coordinates of the surface element corners whose edges are projected.
corners2	The coordinates of the surface element corners on which is projected.
directions1	The directions along which the projection is done.
gt1	The geometry type of the projected surface element.
gt2	The geometry type of the target surface element.
polygonCorners	If intersection points are found their local coordinates are added to this vector.
hitCorners	Vector containing information on which surface element corners are projected on each other.
neighborIntersects1	If two edges intersect then the corresponding surface element neighbors also intersect. This information for the projected surface element is stored in the bitfield.
neighborIntersects2	If two edges intersect then the corresponding surface element neighbors also intersect. This information for the surface element on which is projected is stored in the bitfield.
overlap	The amount of overlap that is allowed, i.e. projection among the opposite direction is valid if the scaling is smaller than overlap.
