* Name: nxbe_getrectangle
*
* Description:
* Get the raw contents of graphic memory within a rectangular region. NOTE:
* Since raw graphic memory is returned, the returned memory content may be
* the memory of windows above this one and may not necessarily belong to
* this window unless you assure that this is the top window.
*
* Input Parameters:
* wnd - The window structure reference
* rect - The location to be copied
* plane - Specifies the color plane to get from.
* dest - The location to copy the memory region
* deststride - The width, in bytes, of the dest memory
*
* Return:
* None
