checking based on the "search_rang", etc.., fields of
the sfnt header..
This avoids problems (like certain Type 1 multiple masters
incorrectly recognized as trueType files)..
compiler warnings with GCC + "-ansi -pedantic -Wall -W"
and LCC.
Also fixed the compilation of "type1z" with Win32-LCC
(its pre-processor is broken !!)
Updated the BUILD document too
EXPORT_FUNC, BASE_DEF and BASE_FUNC macros to
let them take an argument..
This is needed to compile the library as a DLL on some platforms
that have different compiler conventions..
- modified the interface of the "sfnt" module. There is now a function
called "load_format_tag", and another called "load_directory".
The first one is in charge of returning the 4-byte tag located at
the beginning of a given font file. It understand TrueType collections
and parses them automatically
The second loads the table directory that is located just after
the format tag.
This is useful, because the "SFNT" storage scheme can be used by
several distinct formats, each with its own format tag.
The TrueType driver now checks the format tag in "src/truetype/ttobjs.c"
- made some changes to "src/shared/t1types.h" to clearly separate the
Type 1 font content from the rest of the T1_Face structure. This
will be useful when adding the CFF/Type2 driver that will be able
to reuse the "T1_Font" structure within a "TT_Font" one (which
really describes a SFNT-based font file).
Some changes in "src/type1" were thus performed to reflect this.
Note that the current type1 driver will be discontinued in a
distant future. More on this later..
