Message : 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.
