    For example, if the smallest font is 10x10 and your window is 600x800, you 
will get a glyph matrix of approx 60x80.
    Now, if you use a sliced image (or just many images which are less than 
10x10 in size, you can easily fill the
    window with more than those 60x80 glyphs.

Maybe redisplay should notice when it encounters a glyph below
the size that was used for the calculation of the glyph matrix,
and enlarge the glyph matrix at that point.
