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)..
limit on the number of subglyphs in a TrueType font..
changed the default number of gray levels used by the
smooth renderer to 256 (instead of 128). Of course, the
human eye can't tell a difference ;-)
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..
