I want to design a control that needs to have extra "handles" at design
time.  Basically at design time I want my control to have a line coming off
of it that extends beyond the region of my control and ends in a "gripper"
handle (probably only when it is selected in the form designer).   I want
the user to be able to grab the gripper handle and move it anywhere to
rotate the control as well as specify a distance from the control (by the
length of the line). The rotation of the control isn't a problem, but how do
I create a custom design time behaviour like that that can draw outside the
bounds of the control and allows my control to redraw itself (at design
time)?
