Replace solid black rendering of anti-aliased font edges with period-2 dithering patterns. Full coverage pixels render as solid ink, while partial coverage pixels use checkerboard patterns (50% for dark grey, 25% for light grey) matching fillRectDither behavior. This prevents edge pixels from bolding to black on BW displays and produces proper anti-aliasing for 2-bit fonts.
