freetype.h: Adding ft_encoding_xxx values for some CJK encodings.

Fixing copyright notice on many files.

Changed some tracing levels.

A lot of formatting, fixing documentation etc. as usual.

ftview now has two new options: -d activates debugging, and -l sets the
trace level.

Since FT2 is still beta, I've activated the FT_DEBUG_xxx macros by default.

To make reasonable output, I've changed some TRACEx macros to other levels.

More preparation for tracing.  Formatting.

Finishing first formatting/documenting etc. of the `base' dir.  Some modules
are still badly documented, though...

Added a lot of error checking code to the exported functions in the `base'
subdir (not complete yet).

Formatting, fixing and adding documentation.

fixed some nasty little bugs too

  - the glyph index was not checked in FT_Load_Glyph
  - the "type1" driver didn't read the FontBBox and FontMatrix
    correctly..

reformating/spacing

FT_TRACE calls to use %p instead of %lx when dumping
a pointer address

(at last :-)

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..

to font drivers when creating a new face object.

The FT_Open_Args structure has been changed to simplify
its use and allow generic parameters too..

to unsigned long (easier than string to compare)

  - there is now a "convenience" API to manage glyphs in
   "include/ftglyph.h". See the demo program "ftstring" for
   an example..

  - the raster interface has been changed in order to allow
    direct composition through user-provided callbacks. This
    has been tested but isn't demonstrated for now in "demos"

 - the FT_LOAD_NO_RECURSE flag is supported, as this is
   required by some new code in the auto-hinting engine

 - some bug fixed in FT_MulFix which made FT_xxx_Transform
   return incorrect results..

FT_Outline_<action> syntax..

  - "flags" have been renamed to "tags"
  - "outline_flags" have been renamed to "flags"

Look for more re-formatting today..

all outline flags in a single integer..

Changed the rest of the library and demo programs
accordingly..

- ft_done_stream: remove the FREE(pathname) call, which wasn't
  kosher
- FT_Open_Face: after calling open_face, don't assume driver is
  the same as face->driver, use face->driver instead

added missing "else": without it FT_Open_Face() would still scan the list of drivers when specifying an explicit driver

ft_new_input_stream(): set the pathname field of the stream to args->pathname. Needed for the Mac fond driver.
ft_done_stream(): free the pathname field, if not null

Formatting.  Adding/Fixing documentation.

interface, used to implement FT_Attach_File.

Note, this is currently very lightly tested..

parsing.

Also, changed the API for FT_Open_Face to allow
broader stream descriptions..

  - 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..

ftcalc.c, ftextend.c, ftoutln.c, ftraster.c, ftstream.c:
  Removing trailing spaces.

ftlist.h:
  Removing duplicated documentation (which is in ftlist.c also).

ftinit.c, ftlist.c, ftobjs.c:
  Formatting, adding documentation.
