Patches to the auto-hinter in order to slightly improve the output.
Note that everything is controlled through the new
FT_CONFIG_OPTION_CHESTER_HINTS defined in "ftoption.h". There are
also individual FT_CONFIG_CHESTER_XXX macros to control individual
"features".
Note that all improvements are enabled by default, but can be
tweaked for optimization and testing purposes. The configuration
macros will most likely disappear in the short future.

This allows the build system to define them depending on the
