   @code{open_canvas} opens a canvas, which is a window for drawing objecgts.
   One can specifies the size of a canvas in pixel by
   supplying @var{geometry} option [@var{x},@var{y}]. The default size is
   [@code{300},@code{300}].
   This function pushes an integer value onto the stack of the OpenXM server.
   The value is used to distiguish the opened canvas and one has to pop
   and maintain the value by @code{ox_pop_cmo} for subsequent calls of
   @code{draw_obj}.
