%%%if given the same vector for all four quad arguments mathutils.geometry.intersect_point_quad_2d returns true regardless of what the point vector is.
Since the quad is essentially a point in this case it should probably only return true if the point is also that same vector as the quad.

%%%Since this doesn't seem to be BGE specific, I'm moving it to the general 2.6 tracker where it will get more attention. If it turns out to be a BGE issue, then the report can be moved back to the BGE tracker.%%%

%%%Corrected documentation to this function which matches to how it's internally implemented -- non-concave quads and quads with singularity edges would have inpredictable result.
