Constructs a modification, that transforms the src vectors to the dst vectors. The length of src and dst must be 2. The resulting modification is any kind of an affinity, that projects the src vectors to the dst vectors. The origin (0,0) remains fixed.

Constructs a modification, that transforms the Src points to the Dst points. The length of Src and Dst must be equal and less than 4. If the length is 1, the resulting ModOp is a translation, if the length is 2, the parameter DoScale decides whether the resulting ModOp is a translation and rotation (DoScale==false) or translation, rotation and scaling (DoScale==true). If the length is 3, the resulting modification is any kind of an affinity, that projects the src points to the dst points.
