I think this new property could work well with 'word-spacing' and
'letter-spacing'. I'm less sure about 'text-justify' -- it seems that
it provides conflicting instructions on how to justify. For example,
these are conflicting:

  word-spacing: 0 0 0;
  text-justify: inter-word;

What would be a good name for at new property for glyph scaling?
Glyph-scaling, perhaps?

What knobs do you offer in InDesign?
