Arguments: drawable
Returns the stream that an application should currently draw on for a
drawable. If
the use-bitmap-stream
property of drawable is true, drawable-stream will return the bitmap-stream of
drawable. Otherwise, drawable-stream will return the visible window of
the drawable control.
Note that if drawable is not currently on a dialog and use-bitmap-stream
is false, then nil is returned. This may
cause problems since the appropriate stream is passed automatically to
the drawing functions.
