Using winapi.Polygon looks custom drawn to me, at least under linux and 
windows they are not custom drawn.

Under windows it looks it's drawing unsing DrawFrameControl to draw 
scrollbar arrow (but it's not yet themed, maybe Paul know if can be themed 
if so maybe it should be changed, and that would be if arrows are supposed 
to be scrollbars arrows).

Under gtk, TArrow is drawn using native widget and I guess it's the origin 
of this component.

in neither gtk or windows was able to draw any frame, in fact I don't know 
what ShadowType means, will try to find out next time I boot linux.
