I think this should be SetShowMultipleIconStates to make it clear this is
applying to the button icon.

Also, the comment would then read something like:

// Sets whether or not to show the hot and pushed states of the button icon (if
present) in addition to the normal state. Defaults to true.

 
   // Paint the button into the specified canvas. If |for_drag| is true, the
   // function paints a drag image representation into the canvas.
