/**

* image data from a server-side drawable to a client-side RGB(A) buffer.
* This allows you to efficiently read individual pixels on the client side.
*
* This function will create an RGB pixbuf with 8 bits per channel with

*
* If the window is off the screen, then there is no image data in the
* obscured/offscreen regions to be placed in the pixbuf. The contents of
* portions of the pixbuf corresponding to the offscreen region are undefined.
*
* If the window you’re obtaining data from is partially obscured by
* other windows, then the contents of the pixbuf areas corresponding
* to the obscured regions are undefined.
*
* If the window is not mapped (typically because it’s iconified/minimized
* or not on the current workspace), then %NULL will be returned.
*
* If memory can’t be allocated for the return value, %NULL will be returned
* instead.
*
* (In short, there are several ways this function can fail, and if it fails
* it returns %NULL; so check the return value.)
