Please retry with the current git.  Three days ago I've committed the
following:

  [truetype] Fix phantom point handling.
    
    This is a further improvement to the changes from 2013-11-06.
    
    * src/truetype/ttgload.c (TT_Hint_Glyph): Horizontal phantom points
    are rounded horizontally, vertical ones are rounded vertically.
    (TT_LOADER_SET_PP): The horizontal position of vertical phantom
    points in pre-ClearType mode is zero, as shown in the OpenType
    specification.

Indeed, it seems that ftgrid now handles your examples just fine.

I think that this is obscure code which should be removed altogether
since phantom points are now properly rounded.
