You might have a look at the auto-hinter code which is related to
FreeType's `warper' option:

  /*************************************************************************/
  /*                                                                       */
  /* Compile autofit module with warp hinting.  The idea of the warping    */
  /* code is to slightly scale and shift a glyph within a single dimension */
  /* so that as much of its segments are aligned (more or less) on the     */
  /* grid.  To find out the optimal scaling and shifting value, various    */
  /* parameter combinations are tried and scored.                          */
  /*                                                                       */
  /* This experimental option is only active if the render mode is         */
  /* FT_RENDER_MODE_LIGHT.                                                 */
  /*                                                                       */
/* #define AF_CONFIG_OPTION_USE_WARPER */

Any improvements to this code are highly welcomed :-)
