  Hash : 2aa2aeb5
  Message : * Move include/* to src/FTGL/* so the files in there can directly be referred to as "FTGL/*.h". This is convenient because they will be installed in a similar location. * Put a warning in each legacy public header to advise users to only include the generic <FTGL/ftgl.h> header instead.
