* builds/win32/detekt.mk: Fix .PHONY target for Intel compiler. Renamed "ftnames.h" to "ftsnames.h", and FT_NAMES_H to FT_SFNT_NAMES_H. * docs/docmaker.py: Added generation of INDEX link in table of contents. * INSTALL, docs/BUILD: Updated documentation to indicate that the compilation process has changed slightly (no more `src' required in * builds/*/*-def.mk: Changed the objects directory from "obj" to "objs". * include/freetype/config/ftheader.h: Removed obsolete macros like FT_SOURCE_FILE, etc. and added cache-specific macro definitions that were previously defined in <freetype/ftcache.h>. Added comments to be included in a new API Reference section. * src/*/*: Removed the use of FT_SOURCE_FILE, etc. Now, each component needs to add its own directory to the include path at compile time. Modified all "rules.mk" and "descrip.mms" accordingly. * src/cid/cidobjs.c, src/cid/cidload.c, src/pcf/pcfread.c, src/type1/t1load.c, src/type1/t1objs.c: Added a few casts to remove compiler warnings in pedantic modes. * include/config/ft2build.h, include/config/ftheader.h: The file top-level <ft2build.h>. * include/config/ftheader.h: Added new section describing the #include macros. the Type 2 glyph charstring (used by conversion programs). * docs/docmaker.py: Added cross-references generation as well as seac emulation provided by the Type 2 endchar operator. * src/cid/cidafm.c, src/cid/cidafm.h: removed un-needed files, Added support for clipped direct rendering in the smooth renderer. * src/cff/t2objs.c (T2_Init_Face): For pure CFF fonts, set

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.

(CFF_FontRec): Add `num_strings', `strings', and `string_pool' fields. Remove `string_index' and `num_global_subrs' fields. Use real types instead of `void' for `pshinter' and `psnames' fields. * src/cff/cffload.c: Don't include PS cmaps service. (cff_index_get_pointers): Add `pool' parameter which allows to insert an extra NUL character for each String INDEX entry. (cff_index_get_name): Make it a local function. (cff_index_get_string): New function. (cff_subfont_load): Updated. (cff_font_load): Initialize `num_strings', `strings', and `string_pool' fields in the `CFF_FontRec' structure. (cff_index_get_sid_string): Use `cff_index_get_string' instead of `cff_index_get_name'. (cff_font_done): Updated. * src/cff/cffload.h: Don't include PS cmaps service. (cff_index_get_string): Added. (cff_index_get_sid_string): Updated. * src/cff/cffobjs.c: Don't include PS cmaps service and FT_INTERNAL_POSTSCRIPT_HINTS_H. (cff_size_get_globals_funcs, cff_slot_init): Updated.

[cff] Implement CFF2 support (2/2). The font variation code. All parts dependent on the GX code in the `truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT. In other words, you can still compile the `cff' module without defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2 support without font variation). * src/cff/cf2font.c (cf2_font_setup): Add support for font variation. * src/cff/cf2font.h (CF2_Font): Add fields for variation data. * src/cff/cf2ft.c (cf2_free_instance): Free blend data.

Updated. * src/cff/cffobjs.c (cff_face_done): Updated. * src/cff/cffparse.c: Include `cffload.h'. (cff_parse_num): Handle internal value 255. (cff_parse_vsindex, cff_parse_blend): New functions. (CFF_FIELD_BLEND): New macro. (cff_parser_run): Updated. * src/cff/cffparse.h (cff_kind_blend): New enum value. * src/cff/cfftoken.h: Handle `vstore', `vsindex', and `blend' dictionary values. * src/cff/cfftypes.h (CFF_VarData, CFF_AxisCoords, CFF_VarRegion, CFF_VStore, CFF_Blend): New structures.

(CFF_Font): Add `vstore' field. * src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar', since glyph variation data is directly embedded. (TT_Set_MM_Blend): Don't load `gvar' table for CFF2 fonts.

Improve CFF string (especially glyphname) lookup performance. We do this by avoiding memory allocation and file I/O. This is Savannah patch #7104. * src/cff/cfftypes.h: Include PS cmaps service and FT_INTERNAL_POSTSCRIPT_HINTS_H. (CFF_SubFontRec): Remove `num_local_subrs'. (CFF_FontRec): Add `num_strings', `strings', and `string_pool' fields. Remove `string_index' and `num_global_subrs' fields. Use real types instead of `void' for `pshinter' and `psnames' fields. * src/cff/cffload.c: Don't include PS cmaps service. (cff_index_get_pointers): Add `pool' parameter which allows to insert an extra NUL character for each String INDEX entry. (cff_index_get_name): Make it a local function. (cff_index_get_string): New function. (cff_subfont_load): Updated. (cff_font_load): Initialize `num_strings', `strings', and `string_pool' fields in the `CFF_FontRec' structure. (cff_index_get_sid_string): Use `cff_index_get_string' instead of `cff_index_get_name'. (cff_font_done): Updated. * src/cff/cffload.h: Don't include PS cmaps service. (cff_index_get_string): Added. (cff_index_get_sid_string): Updated. * src/cff/cffobjs.c: Don't include PS cmaps service and FT_INTERNAL_POSTSCRIPT_HINTS_H. (cff_size_get_globals_funcs, cff_slot_init): Updated.

[cff] Add a new Type 2 interpreter and hinter. This work, written by Dave Arnold <darnold@adobe.com> and fully integrated into FreeType by me, is a donation by Adobe in collaboration with Google. It is vastly superior to the old CFF engine, and it will replace it soon. Right now, it is still off by default, and you have to explicitly select it using the new `hinting-engine' property of the cff driver. For convenience, (most of) the new files are committed separately. * include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro. * include/freetype/ftcffdrv.h: New file to access CFF driver properties. * include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error code. * include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints', and `cf2interp'. * src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'. * src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine' and `no_stem_darkening'. * src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'. * src/cff/cff.c: Include new files. * src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle `hinting-engine' and `no-stem-darkening' properties (only the Adobe engine listens to them). * src/cff/cffgload.c: Include `cf2ft.h'. (cff_decoder_prepare): Initialize `current_subfont'. (cff_build_add_point): Handle Adobe engine which uses 16.16 coordinates. (cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING separately. Choose rendering engine based on `hinting_engine' property. * src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe engine. * src/cff/cffobjs.c: Include FT_CFF_DRIVER_H. (cff_driver_init): Set default property values. * src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files. * src/cff/cf2*.*: New files, containing the Adobe engine.
