Big improvements to font rendering

The previous rasterizing code relied on each row in the font being 8
bits wide, which is not the case with any font wider than 8 pixels.
These changes make it possible to properly load the 24px Terminus font,
and somehow also fixes incorrect characters in the 12px font.
