Notes

Index returned begins at 0, but could be negative. -1 If X,Y is not contained in a triangle (or triangle not found) -2 If the location is on an edge This is for "fall-back" purposes only. Frequently edge positions are located as being part of a triangle, so do not rely on this result to determine if a node position is on an edge. -3 If the location is a vertex. This is for "fall-back" purposes only in the code. Normal operation is to include a node position inside a triangle, so do not rely on this result to determine if a node position is input.
