Convenient way to determine exact point under mouse

Is it also possible with TransformUnderMouse to detect if part of the underlying transform part is transparant? So that it only reacts if mouse is moving over a part that is not transparant?

To anyone following this thread and looking for a solution to this, i.e. “query object under mouse in a way that avoids selecting a polygon with transparent pixels” – see TransformUnderMouse with Alpha pixels check for quad-based Transforms where @phomm has presented a working solution with demo (and I proposed some improvements to make it even simpler ).
