handler to connect buttons with a line

[Malte Brill]

Hi Kersten,

on card level:

on moveControl
   set the points of grc 1 to the loc of btn 1&cr&the loc of btn 2
end moveControl

This is not moving the line while dragging though. Stuff to handle that indedd is in AE (Thanks for the plug Jim!)

Cheers,

Malte
