Creates a window with a black-and-yellow striped frame around it.
When grabbed at this frame, the window can be dragged around the screen.

HJG Maybe the definition of the stripe-pattern could be made more compact with lrepeat ?
PWQ '19 Jul 05, I have two options for borders, the offset'' parameter is to allow recreating the images to animate the frame. Like the -dash offset used for marching ants.

escargo 13 Jul 2005 - Just so you can quit it...
bind all <Key-q> { exit } .can create text 110 80 -text "Press Q to quit" -anc nw
PWQ 15 Jul 05, Lets cut down on the number of images needed to render the border.

Note on FWVM override prevents window from taking focus so it cannot receive key press events
