Add new anti-aliased (smooth) font examples + bug fixes

Browse Source 
Four new examples have been added to show different methods of rendering
the anta-aliased fonts.  A few minor bugs have been corrected associated
with the font rendering. drawNumber and drawFloat handle fixed width
mono fonts with no digit movement.
