Treat all size related properties as unsigned values.
* src/pcf/pcf.h (PCF_ParsePropertyRec): Use unsigned `name' and
`value'.
* src/pcf/pcfread.c (pcf_get_propeerties, pcf_load_font): Updated
parsing code and handling of AVERAGE_WIDTH, POINT_SIZE, PIXEL_SIZE,
RESOLUTION_X and RESOLUTION_Y.
Unofficial specifications hesitate to use unsigned 32-bit integers.
Negative values caused a lot of trouble in the past and it is safer
and easier to treat some properties as unsigned.
* src/pcf/pcf.h (PCF_AccelRec): Use unsigned values for `fontAscent',
`fontDescent', and `maxOverlap'.
* src/pcf/pcfread.c (pcf_load_font, pcf_get_accel): Updated.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load, PCF_Size_Select,
PCF_Size_Request): Updated.
This change makes the driver use the `defaultChar' property of PCF
files.
* src/pcf/pcf.h (PCF_FaceRec): Change type of `defaultChar' to
unsigned.
* src/pcf/pcfread.c (pcf_get_encodings): Read `defaultChar' as
unsigned.
Validate `defaultChar'.
If `defaultChar' doesn't point to glyph index zero, swap glyphs with
index zero and index `defaultChar' and adjust the encodings
accordingly.
* src/pcf/pcfdrivr.c (pcf_cmap_char_index, pcf_cmap_char_next,
PCF_Glyph_Load): Undo change from 2002-06-16 which always enforced
the first character in the font to be the default character.
The change from 2016-09-29 was too radical (except for people using
the openSuSE GNU/Linux distribution). To ameliorate the situation,
PCF_CONFIG_OPTION_LONG_FAMILY_NAMES gets introduced which controls
the feature; if set, a new PCF property option
`no-long-family-names' can be used to switch this feature off.
* include/freetype/config/ftoption.h, devel/ftoption.h
(PCF_CONFIG_OPTION_LONG_FAMILY_NAMES): New option.
* include/freetype/ftpcfdrv.h: New header file (only containing
comments currently, used for building the documentation).
* include/freetype/config/ftheader.h (FT_PCF_DRIVER_H): New macro.
* src/pcf/pcf.h (PCF_Driver): Add `no_long_family_names' field.
* src/pcf/pcfdrivr.c: Include FT_SERVICE_PROPERTIES_H and
FT_PCF_DRIVER_H.
(pcf_property_set, pcf_property_get): New functions.
(pcf_service_properties): New service.
(pcf_servives): Updated.
(pcf_driver_init) [PCF_CONFIG_OPTION_LONG_FAMILY_NAMES]: Handle
`no_long_family_names'.
* src/pcf/pcfread.c (pcf_load_font): Handle `no_long_family_names'
and PCF_CONFIG_OPTION_LONG_FAMILY_NAMES.
* docs/CHANGES: Updated.
To be filled later on with something useful.
* src/pcf/pcf.h (PCF_Driver): New structure.
* src/pcf/pcfdrivr.c (pcf_driver_init, pcf_driver_done): New dummy
functions.
(pcf_driver_class): Updated.
Similar to other font formats, this commit makes the parser no
longer check the whole PCF file but only the header and the TOC if
we just want to get the number of available faces (and a proper
recognition of the font format).
* src/pcf/pcfdrivr.c (PCF_Face_Init): Updated.
Exit quickly if face_index < 0.
* src/pcfread.c (pcf_load_font): Add `face_index' argument.
Exit quickly if face_index < 0.
* src/pcf/pcf.h: Updated.
src/base/ftbdf.c, src/bdf/bdfdrivr.c, src/pcf/pcfdrivr.c,
src/pcf/pcfread.h:
adding a new API, named FT_Get_BDF_Property to retrieve the BDF
properties of a given PCF or BDF font
* 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 added its own directory to the include path at compile time.
Modified all "rules.mk" and "descrip.mms" accordingly..
