Complete redesign of error codes. Please check ftmoderr.h for more details. * include/freetype/internal/cfferrs.h, include/freetype/internal/tterrors.h, include/freetype/internal/t1errors.h: Removed. Replaced with files local to the module. All extra error codes have been moved to `fterrors.h'. * src/sfnt/ttpost.h: Move error codes to `fterrors.h'. * src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h, src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h, src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h, src/smooth/ftsmerrs.h, src/truetype/tterrors.h, src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the error names for the module it belongs to. * include/freetype/ftmoderr.h: New file, defining the module error offsets. Its structure is similar to `fterrors.h'. * include/freetype/fterrors.h (FT_NOERRORDEF): New macro. (FT_ERRORDEF): Redefined to use module error offsets. All internal error codes are now public; unused error codes have been removed, some are new. * include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New macro. * include/freetype/config/ftoption.h (FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro. All other source files have been updated to use the new error codes; some already existing (internal) error codes local to a module have been renamed to give them the same name as in the base module. All make files have been updated to include the local error files. * src/cid/cidtokens.h: Replaced with... * src/cid/cidtoken.h: This file for 8+3 consistency. * src/raster/ftraster.c: Use macros for header file names.

A new try to synchronize bitmap font access. include/freetype/freetype.h (FT_Bitmap_Size): `height' is now defined to return the baseline-to-baseline distance. This was already the value returned by the BDF and PCF drivers. The `width' field now gives the average width. I wasn't able to find something better. It should be taken as informative only. New fields `size', `x_ppem', and `y_ppem'. * src/pcf/pcfread.c (pcf_load_font): Updated to properly fill FT_Bitmap_Size.

Redesigning the FNT driver to return multiple faces, not multiple strikes. At least one font (app850.fon from WinME) contains different FNT charmaps for its subfonts. Consequently, the previous design of having multiple bitmap strikes in a single font face fails since we have only one charmap per face. * include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed. (FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with `font'. * src/base/ftwinfnt.c (FT_Get_WinFNT_Header): Updated. * src/winfonts/winfnt.c (fnt_font_load): Don't set pixel_width equal to pixel_height.

(fnt_font_done, FNT_Face_Done): Updated. (FNT_Face_Init): Handle `face_index'. Updated. (FNT_Size_Set_Pixels): Simplified; similar to BDF and PCF, the bitmap width is now ignored.

A new try to synchronize bitmap font access. include/freetype/freetype.h (FT_Bitmap_Size): `height' is now defined to return the baseline-to-baseline distance. This was already the value returned by the BDF and PCF drivers. The `width' field now gives the average width. I wasn't able to find something better. It should be taken as informative only. New fields `size', `x_ppem', and `y_ppem'. * src/pcf/pcfread.c (pcf_load_font): Updated to properly fill FT_Bitmap_Size. Do proper rounding and conversion from 72.27 to 72 points. * src/bdf/bdfdrivr.c (BDF_Face_Init): Updated to properly fill FT_Bitmap_Size. Do proper rounding and conversion from 72.27 to 72 points. * src/sfnt/sfobjs.c (sfnt_load_face): Updated to properly fill FT_Bitmap_Size. * src/winfonts/winfnt.c (FNT_Face_Init): Updated to properly fill FT_Bitmap_Size. Redesigning the FNT driver to return multiple faces, not multiple strikes. At least one font (app850.fon from WinME) contains different FNT charmaps for its subfonts. Consequently, the previous design of having multiple bitmap strikes in a single font face fails since we have only one charmap per face. * include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed. (FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with `font'. * src/base/ftwinfnt.c (FT_Get_WinFNT_Header): Updated. * src/winfonts/winfnt.c (fnt_font_load): Don't set pixel_width equal to pixel_height. (fnt_face_done_fonts): Removed. (fnt_face_get_dll_fonts): Renamed to... (fnt_face_get_dll_font): This. Add second function argument to select face index. Updated to load just one subfont. (fnt_font_done, FNT_Face_Done): Updated. (FNT_Face_Init): Handle `face_index'. Updated. (FNT_Size_Set_Pixels): Simplified; similar to BDF and PCF, the bitmap width is now ignored. (FNT_Load_Glyph): Updated. Fix glyph index computation. (winfnt_driver_class): Updated.
