Checking the code, it seems that the light hinter is already used in 
dvipng (with a differently named compile-time const), while the default 
lcd filter is not used. Since dvipng is not a display renderer and 
cannot know beforehand if rendering is done for an LCD display or not, I 
doubt that this is really an option.
