Rendering the glpyhs at 128x128 and storing it 1 bit per pixel on the card, 
and using that to draw all sizes up to perhaps 64x64, and using normal 
path-filling for any larger sizes, would probably use far less memory 
than the current scheme of storing 8 bit versions of the glyphs at many 
different sizes.

The trick is that the scaling hardware must be fast enough, but I suspect on 
modern cards this is no problem. A screen full of text would contain on the 
order of tens of thousands of characters, and we are talking about graphics 
hardware that can now draw a million texture-mapped triangles in one screen 
retrace.
