Very wide windows

[Dean P McCullough <dpmccul comcast net>]

I have an application that is too wide to fit on a single screen.  I 
would like to make use of the multiple screens available in most Linux 
distributions.  Unfortunately, when the gtk application opens, I have to 
drag the right hand border into the next screen to see all of the image.

Is there a reasonable way to either open multiple windows (I suspect 
that this is contrary to the philosophy behind gtk) or to force it to 
make the image wider than the screen resolution (and thus part of the 
image would be in the second screen)?

Thanks
