Detecting the mouse, yes, always.  But within an irregular polygon shape,
the mouse would be detected using the entire rect of the graphic, regardless
of any concave or convex regions.  I (and Eric Chatonet I assume) spent many
years working around this limitation by using images with transparent
regions.  But this is now irrelevant as graphics detect the mouse using only
the area they occupy as expected.
