    [truetype] Improve emulation of vertical metrics.
    
    This commit also improves the start values of vertical phantom
    points.  Kudos to Greg Hitchcock for help.
    
    * src/truetype/ttgload.c (TT_Get_VMetrics): Add parameter to pass
    `yMax' value.  Replace code with fixed Microsoft definition.
    (tt_get_metrics): Updated.
    (TT_LOADER_SET_PP): Add explanation how to initialize phantom
    points, taken from both the OpenType specification and private
    communication with Greg (which will eventually be added to the
    standard).
    Fix horizontal position of `pp3' and `pp4'.
    
    * src/truetype/ttgload.h: Updated.
    
    * src/truetype/ttdriver.c (tt_get_advances): Updated.
    
    * docs/CHANGES: Updated.
