I think we're making this WAY too difficult and hackish with DC 
size/position calculations all over the place.

I suggest making the grabbers windows, derivative of a TCustomForm or so.

I suggest using a window, derivative of TCustomForm, for drawing 
invisible components on.

Then it'll all be easier and cleaner. What do you think?
