+ * 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, the the dest memory
+ *
+ * Return:
+ *   None
