Turn down subpixel accuracy to 1/8th pixel

Using the full accuracy range of 1/64th pixel seems unnecessary--1/8th
pixel is "good enough".  Mask out the three lowest bits to lower cache
and CPU usage; a short test shows that this almost halves the amount
of glyphs with different subpixel shifts being generated and cached.
