  [smooth] Formalize Harmony LCD rendering.
  
  This generalizes magic outline shifts that make Harmony LCD
  rendering work in terms of precise two-dimensional RGB subpixel
  positions. These coordinates are now set in time of the `smooth'
  module initialization and later used to shift a glyph outline for
  rendering. FT_RENDER_MODE_LCD and FT_RENDER_MODE_LCD_V use the same
  coordinates. The letter, however, rotates them before using.
  The LCD bitmap padding is also calculated using these coordinates.
  
  * include/freetype/internal/ftobjs.h (FT_LibraryRec): New array field
  `lcd_geometry'.
  * src/base/ftlcdfil.c (ft_lcd_padding): Reworked.
  * src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Updated accordingly.
  
  * src/smooth/ftsmooth.c [!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]
  (ft_smooth_init): Initialize `lcd_geometry'.
  (ft_smooth_render_generic): Formalize outline shifts.
