[Mapserver-dev] jBox image dragging

[Steve Lime]

Cool, nice modification, now of course I need to modify dbox. There is
no problem sending
negative coordinates. That's how most panning is done anyways.

I have added image dragging functionality to jBox. This allows the user
to 
drag the image within the applet area. A new imgxy is then passed to 
mapserver when the mouse is released. A working example is at 
http://www2.tetonwyo.org/mapserver/ 

Depending on how far the user has dragged the image, the new values for

imgxy may be negative and/or greater than the current image size. In my

limited testing this has not generated any errors. Does anyone see a 
problem with this? i.e. Am I breaking any rules by sending negative
imgxy 
values, or imgxy values greater than the current image size?

Thanks,
Rich
