Off-screen drawing of GTK widgets

["Varun Khaneja" <khaneja gmail com>]

Hello,

I have been trying to find out about
the support of off-screen drawing of GTK widgets using Cairo (or any
other library), but haven't been much successful.
What I really need to do is to be able to capture the image of the widget
without actually showing
it on the screen, which is called off-screen drawing (if my undersanding is
correct).

Towards this, any pointers would be very much appreciated.

Thanks,
Varun
