Slip, sliding away

[Richmond]

I made a loooong rectangular image (3 times wider than my stack) and 
grouped it

into a group the width of my stack and gave it a horizontal scrollbar; 
so I can scroll the image

laterally using the scrollbar . . . surprise, surprise; and jolly s*xy 
it looks too.

I would look even s*xier if it had NO scrollbar and I could do some sort of

'constrained grab'/scroll by doing a mouseDown & horizontal drag on the 
image within the group.


Does anyone know how to do this.

Just to stimulate interest, the reason is that I want to do this sort of 
thing
