* This function will (1) clip that src rectangle so that it lies within

* destrect - The location to receive the clipped rectangle relative
* to containing window
* destoffset - The location to received the clipped offset.
* srcrect - Describes the rectangular region relative to the client
* sub-window to move relative to the sub-window
* srcoffset - The offset to move the region
* bounds - The subwindow bounds in absolute screen coordinates.
*
* Returned Value:
* OK on success; ERROR on failure with errno set appropriately
