  Avoid overwriting of numeric font dictionary entries for synthetic
  fonts. Additionally, some entries were handled as `integer' instead
  of `number'.
  
  * include/freetype/internal/psaux.h (T1_FieldType): Add
  T1_FIELD_TYPE_BOOL_P, T1_FIELD_TYPE_INTEGER_P, and
  T1_FIELD_TYPE_FIXED_P.
  (T1_FIELD_BOOL_P, T1_FIELD_NUM_P, T1_FIELD_FIXED_P): New macros.
  * src/psaux/psobjs.c (ps_parser_load_field): Handle new field types.
  
  * include/freetype/internal/cfftypes.h (CFF_FontRecDict),
  src/cff/cfftoken.h: Change type of underline_position and
  underline_thickness to FT_Fixed.
  * src/cff/cffload.c (cff_subfont_load): Fix default values of
  underline_position and underline_thickness.
  * src/cff/cffobjs.c (cff_face_init): Set underline_position
  and underline_thickness in `root'.
  
  * include/freetype/internal/t1types.h (T1_Font): Change point_type
  and stroke_width to pointers.
  * include/freetype/t1tables.h (PS_FontInfo): Change italic_angle,
  is_fixed_pitch, underline_position, and underline_thickness to
  pointers.
  * src/type1/t1tokens.h: Change italic_angle, is_fixed_pitch,
  underline_position, and underline_thickness to pointers.  Change
  the type of the latter two to `fixed'.
  Change type of stroke_width to `fixed' and make it a pointer.
  Change paint_type to pointer.
  * src/type1/t1objs.c (T1_Face_Done): Updated.
  (T1_Face_Init): Updated.
  Fix assignment of underline_position and underline_thickness.
  
  * src/cid/cidtoken.h: Change italic_angle, is_fixed_pitch,
  underline_position, and underline_thickness to pointers.  Change
  the type of the latter two to `fixed'.
  Change type of stroke_width to `fixed'.
  * src/cid/cidobjs.c (cid_face_done): Updated.
  (cid_face_init): Updated.
  Fix assignment of underline_position and underline_thickness.
  
  * src/type42/t42parse.c: Change italic_angle, is_fixed_pitch,
  underline_position, and underline_thickness to pointers.  Change the
  type of the latter two to `fixed'.
  Change type of stroke_width to `fixed' and make it a pointer.
  Change paint_type to pointer.
  * src/type42/t42objs.c (T42_Face_Init): Updated.
  Fix assignment of underline_position and underline_thickness.
  (T42_Face_Done): Updated.
  
  * src/base/ftobjs.c (open_face_from_buffer): Fix compiler warning.
  * src/pshinter/pshglob.c, src/pshinter/pshglob.h
  (psh_globals_set_scale): Make it a local function.
  
  * test/gview.c: Fix remaming ps3->ps typo.
  Formatting.
