set-media

Sets the buffer that is viewed by the canvas, releasing the current buffer (if any). If the new buffer already has an administrator that is not associated with a wx:media-canvas%, then the new buffer is not installed into the canvas.

• (send a-wx:media-canvas set-media edit redraw) -> void
      edit : wx:media-buffer% object or null
      redraw = #t : boolean

  If redraw is #f, then the buffer is not immediately drawn; in this case, something must force a redraw later (e.g., a call to the on-paint method).
