Problem reported by Del Merritt <del@alum.mit.edu>.
* builds/unix/configure.raw <cpp computation of bit length>: Don't
remove existing FreeType configuration files.
* src/cff/cffload.c (cff_font_load): Separate subfont and face
index handling to load both pure CFFs with multiple subfonts and
OTCs (with multiple faces where each face holds exactly one
subfont).
* src/cff/cffobjs.c (cff_face_init): Updated.
* src/base/ftoutln.c (FT_Outline_EmboldenXY): Replace sequential
calls to FT_MulFix and FT_DivFix with FT_MulDiv.
Mention that bisectors are used to figure out the shift direction.
* src/psaux/psconv.c (PS_Conv_Strtol): Always parse complete number,
even in case of overflow.
(PS_Conv_ToInt): Only increase cursor if parsing was successful.
(PS_Conv_ToFixed): Ditto.
Trace underflow and data error.
Such fonts only have a `cmap' and a `CFF' table.
* src/sfnt/ttload.c (tt_face_load_font_dir): Don't call
`check_table_dir' if font signature is `OTTO'.
* src/psaux/psconv.c: Include FT_INTERNAL_DEBUG_H.
(FT_COMPONENT): Define.
(PS_Conv_Strtol): Return FT_Long.
Handle bad data and overflow.
Emit some tracing messages in case of error.
(PS_Conv_ToInt): Return FT_Long.
(PS_Conv_ToFixed): Updated.
* src/psaux/psconv.h: Updated.
* include/freetype/internal/fttrace.h: Add `psconv'.
* src/autofit/aflatin.c, src/autofit/aflatin2.c: Include
`afglobal.h'.
* src/autofit/afloader.c: Fix order of header files.
* src/autofit/afmodule.c: Include `afglobal.h' and `aferrors.h'.
* src/cff/cffparse.c (cff_parse_integer): Emit tracing message in
case of error.
(cff_parse_real): Handle and trace overflow, underflow, and bad data
consistently.
(do_fixed): New helper function, handling and tracing overflow.
(cff_parse_fixed, cff_parse_fixed_scaled): Use `do_fixed'.
* src/truetype/ttinterp.c (Ins_ISECT): Use angle between vectors to
avoid grazing intersections. The previous threshold was too coarse,
incorrectly rejecting short but valid vectors.
`rm -f' is directly used in the `configure' script created by
autoconf, thus no availability test is necessary.
* builds/unix/configure.raw (RMF): Remove test.
* builds/unix/unix-def.in (DELETE): Updated.
* src/autofit/aftypes.h (AF_SCRIPT):
s/AF_SCRIPT_NONE/AF_SCRIPT_DUMMY/. We already use `AF_SCRIPT_NONE'
as a bit mask.
* src/autofit/afdummy.c: Updated.
This is an improved version of a similar fix contained in the
so-called `Infinality patch', taken from
http://www.infinality.net/fedora/linux/zips/freetype-infinality-2.4.10-20120616_01-x86_64.tar.bz2
which addresses various enhancements of the auto-hinter. Without
properties to control a module's metadata it wasn't possible to
adapt the patches because everything was originally controlled by
environment variables which I consider not suitable in general.
A patch to control `increase_x_height' follows.
* src/autofit/afglobal.h (AF_PROP_INCREASE_X_HEIGHT_MIN,
AF_PROP_INCREASE_X_HEIGHT_MAX): New macros.
(AF_FaceGlobalsRec): Add `increase_x_height' member.
* src/autofit/afglobal.c (af_face_globals_new): Initialize it.
* src/autofit/aflatin.c (af_latin_metrics_scale_dim),
* src/autofit/aflatin2.c (af_latin2_metrics_scale_dim): Implement
handling of `increase_x_height'.
The auto-hinter's latin module only handles latin ligatures in the
`Alphabetical Presentation Forms' block.
* src/autofit/aflatin.c (af_latin_uniranges): Fix it.
We want to access the (not yet existing) module's global data later
on.
* src/autofit/afloader.c: Include `afmodule.h'.
(af_loader_init, af_loader_reset, af_loader_done,
af_loader_load_glyph): Change accordingly.
* src/autofit/afmodule.c (AF_ModuleRec): Move to `afmodule.h'.
Updated.
* src/autofit/afmodule.h: Include `afloader.h'.
(AF_ModuleRec): Define here.
* src/autofit/afloader.h (AF_Module): Define here.
Updated.
No properties are added yet.
* src/autofit/afmodule.c: Include FT_SERVICE_PROPERTIES_H.
(af_property_set, af_property_get): New dummy functions.
(af_service_properties, af_services, af_get_interface): Provide
service setup.
(autofit_moduleclass): Add service interface.
* src/autofit/afpic.c: Add necessary forward declarations.
(autofit_module_class_pic_init): Add code for service addition.
(autofit_module_pic_free): Add code for service removal.
* src/autofit/afpic.h (AF_SERVICES_GET, AF_SERVICE_PROPERTIES_GET):
New macros which provide necessary syntactical sugar for PIC
support.
* include/freetype/fterrdef.h (FT_Err_Missing_Property): New error
code.
* include/freetype/ftmodapi.h (FT_Property_Set, FT_Property_Get):
New API.
* include/freetype/internal/services/svprop.h: New file.
* include/freetype/internal/ftserv.h (FT_SERVICE_PROPERTIES_H): New
macro.
* src/base/ftobjs.c: Include FT_SERVICE_PROPERTIES_H.
(ft_property_do, FT_Property_Set, FT_Property_Get): New functions.
