I don't think we did.  But frame size can't in general stay constant as we
have wm hints.  For example, I have 13 pixels of text height.  That gives min
resize 13.  The tool bar is 36 pixels.  So when the tool bar goes, either we
increase text size by 3 (== 39, 3 additional pixels) or by 2 (26, decrease by
10 pixels).

I'll implement whatever seems easiest, and then people can suggest
alternatives after that.
