Fix hinting and add subpixel to SampleApp.

This change allows users of SampleApp to cycle through all of the hinting modes
(using the 'h' key) and also toggle subpixel positioning on the paint (using
the 's' key). Because 'up' and 'down' have replaced its functionality,
'scale', the exising user of 's', is removed.
