GETFRAME Get movie frame.
	GETFRAME returns a column vector with one movie frame. The
	frame is a snapshot (pixmap) of the current axis. GETFRAME
	is usually used in a FOR loop to assemble movie matrix M 
	for playback using MOVIE.  For example:

	   M = moviein(n);
	   for j=1:n
	      plot_command
	      M(:,j) = getframe
	   end
	   movie(M)

	It is important to preallocate movie matrix M before building the
	movie in order to prevent excessive memory use. The function
	MOVIEIN is available for this purpose.

	GETFRAME(H) gets a frame from object H, where H is a handle
	to the root, a figure, or an axis.
	GETFRAME(H,RECT) specifies the rectangle to copy the bitmap
	from, relative to the lower-left corner of object H and in
	the units of its Units property.

	See also MOVIE, MOVIEIN.
