[DUG] Drag and Drop from explorer

[Myles Penlington]

Just use the parents window handle, and then check if the mouse falls
within the graphic control boundaries. Windows only knows about controls
that have handles. Graphic controls etc are in essence just a Delphi
painting layer on top of a windowed control.

I want to be able to drop files from windows explorer onto a 
TGraphicControl and haven't seen any way to do this.  It's really easy 
if you have a handle (such as a panel).

The only solution I can find is to put a panel behind the 
TGraphicControl, but I have 20 of these controls and it would just be a 
pain to insert panels as their parent (I suppose I could cheat and add 
them programatically).
