:as a SuperBitmap window, except the superbitmap would be a text buffer which
:is MUCH shorter than a bitmap the whole screen size.  I find many programs,
:including the CLI, DME, and most text-oriented programs always use smart
:refresh windows, which takes up mucho mem.  If they're going to just use the
:same font anyway, why not do it efficiently?  AmigaBASIC does it that way,
:although it's rather slow.  This would have another advantage over normal

	A SMART_REFRESH window only takes up memory (compared to a 
SIMPLE_REFRESH window) when it is obscured by other windows.  Most of
us use SMART_REFRESH windows for the following reasons:

	-You can use ScrollRaster() with SMART.  There are problems with
	 SIMPLE.  

	-SMART windows are much faster than SIMPLE windows when it comes
	 to resizing/depthcontrol/moving them. 

	-Since the program must refresh SIMPLE windows, if you've got a 
	 lot of SIMPLE windows around things get *real* slow on said
	 operations.

	-Handling REFRESH events is a bitch, and slow, and I have gotten
	 used to instant response.

	In addition to all of that, I have a vested interest in defending
DME, since I wrote it.  If you are worried about memory use, simply iconify
DME's window(s).  As long as the window you are working on is completely
visible, it takes no extra memory.
