Purpose: GDK currently has wrappers for most of Xlib's drawing functions.
         Currently missing, however, are wrappers for X{Draw,Fill}Rectangles
         and X{Draw,Fill}Arcs (all plural).  Why these were left out is
         beyond me. They are more efficient than multiple calls to their
         singular counterparts (gdk_draw_arc, and gdk_draw_rectangle)
         because (1) there is less function-calling overhead, and (2)
         there is less network traffic (they encapsulate many X server
         requests into one).

Patch Method:
         To apply this patch, the code in each file needs to be
         added to the corresponding files in the GDK source distribution
         as follows:

         xtragdk.h      -> gdk.h
         xtragdktypes.h -> gdktypes.h
         xtragdkdraw.c  -> gdkdraw.c

Thats it!
