Grab a pixmap of a window

[Daniel Kasak <dkasak nusconsulting com au>]

Is there an easy way to grab a pixmap of an entire window's contents
( minus window manager decorations )? I know I can ask the window for
it's allocation details and grab a screenshot of the entire screen and
cut out the bit that I want. But is there a better way?
