This adds the option to pass a subpixel offset when fetching a glyph from a font, this offset is currently snapped to thirds of a pixel (i.e. 0, 0.33, 0.66). This is then used when rasterizing the glyph, which is then cached like usual. Note that when using subpixel offsets you're trading a bit of space for accuracy. With the current third of a pixel offsets you can end up with up to 9 bitmaps per glyph.
