Alexei Podtelezhnikov 6eb6158dd7 [smooth] Faster alternative line renderer.
This implementation renders the entire line segment at once without
subdividing it into scanlines.  The main speed improvement comes from
reducing the number of divisions to just two per line segment, which
is a bare minimum to calculate cell coverage in a smooth rasterizer.
Notably, the progression from cell to cell does not itself require any
divisions at all.  The speed improvement is more noticeable at larger
sizes.

Werner Lemberg 8502c98b15 Fix Savannah bug #45097.
We no longer `pollute' the namespace of possible header file names;
instead we move `ft2build.h' up by one level so that it gets
installed in the default include directory (e.g.,
/usr/local/include).  After this commit, only `ft2build.h' stays in
the compiler's include path.

No visible changes for the user who follows the standard FreeType
header inclusion rules.

* include/*: Move to ...

Behdad Esfahbod b2ba68665f [smooth] Fix uninitialized memory access.
Looks like `ras.span_y' could always be used without initialization.
This was never detected by valgrind before because the library-wide
`raster_pool' was used for the worker object and `raster_pool' was
originally zero'ed.  But subsequent reuses of it were using `span_y'
uninitialized.  With the recent change to not use `render_pool' and
allocate worker and buffer on the stack, valgrind now detects this
uninitialized access.

* src/smooth/ftgrays.c (gray_raster_render): Initialize
`ras.span_y'.
2015-01-14 18:43:13 +01:00
Behdad Esfahbod 747ae2c8aa [smooth] Allocate render pool for smooth rasterizer on the stack.
Instead of using the `render_pool' member of `FT_Library' that is
provided down to the rasterizer, completely ignore that and allocate
needed objects on the stack instead.

With this patch, rasterizing glyphs from different faces from
different threads doesn't crash in the smooth rasterizer.

Werner Lemberg fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.

`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'

subdirectory.

This is essentially a mechanical conversion, adding inclusion of

stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code.  Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

Problems reported by suyu@cooee.cn.

* src/smooth/ftgrays.c (gray_move_to, gray_raster_render): Use
RAS_VAR.
2009-06-19 09:09:34 +02:00
Werner Lemberg b5a460597a Make ftgrays compile with _STANDALONE_ and FT_STATIC_RASTER again.
Problems reported by suyu@cooee.cn.

* src/smooth/ftgrays.c (FT_DEFINE_OUTLINE_FUNCS,
FT_DEFINE_RASTER_FUNCS) [_STANDALONE_]: Define.
[!_STANDALONE_]: Include ftspic.h only here.
(ras): Define/declare after definition of `TWorker'.
Use `RAS_VAR_' where necessary.

Oran Agra c1e22f3986 Position Independent Code (PIC) support in smooth renderer.
* src/smooth/ftsmooth.h declare ft_smooth_renderer_class,
ft_smooth_lcd_renderer_class and ft_smooth_lcd_v_renderer_class
using macros from ftrender.h,
when FT_CONFIG_OPTION_PIC is defined create and destroy
functions will be declared.
* src/smooth/ftsmooth.c when FT_CONFIG_OPTION_PIC is defined
the following structs:
ft_smooth_renderer_class, ft_smooth_lcd_renderer_class
and ft_smooth_lcd_v_renderer_class
will have functions to init or create and destroy them
instead of being allocated in the global scope.
And macros will be used from ftspic.h in order to access
ft_grays_raster from the pic_container (allocated in ftgrays.c).

* src/smooth/ftgrays.h include FT_CONFIG_CONFIG_H
* src/smooth/ftgrays.c when FT_CONFIG_OPTION_PIC is NOT defined
func_interface was moved from gray_convert_glyph_inner function
to the global scope.
When FT_CONFIG_OPTION_PIC is defined
func_interface and ft_grays_raster structs
will have functions to init them
instead of being allocated in the global scope.
And func_interface will be allocated on the stack of
gray_convert_glyph_inner.

New Files:
* src/smooth/ftspic.h declare struct to hold PIC globals for smooth
renderer and macros to access them.
* src/smooth/ftspic.c implement functions to allocate, destroy and
initialize PIC globals for smooth renderer.

* src/smooth/smooth.c add new file to build: ftspic.c.
* src/smooth/jamfile add new files to FT2_MULTI build: ftspic.c.

2002-09-16 06:15:31 +00:00
David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all logical
    transformations of the sources:

      - trying to convert all enums and constants to CAPITALIZED_STYLE, with
        #define definitions like

          #define  my_old_constants   MY_NEW_CONSTANT

      - big, big update of the documentation comments

    * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
    include/freetype/ftimage.h: adding support for LCD-optimized rendering
    though the new constants/enums:

      FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
      FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

    this is still work in progress, don't expect everything to work correctly
    though most of the features have been implemented.

    * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
    targets:

      FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
      FT_LOAD_TARGET_MONO   :: monochrome bitmaps
      FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated hinting & rendering
      FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated hinting & rendering

    note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
    behaviour of the font engine is _unchanged_.

src/base/ftobjs.c, src/objs/fttype1.c, src/sfnt/ttcmap0.c,
    src/smooth/ftgrays.c: changed uses of "setjmp" and "longjmp"
    to "ft_setjmp" and "ft_lonjmp". Removed direct references to
    <stdio.h> and <setjmp.h> when appropriate, to eventually replace
    them with a FT_CONFIG_STANDARD_LIBRARY_H. Useful for the XFree86
    Font Server backend based on FT2.

          src/type1/t1load.c, src/type1/t1objs.c,   src/type1/t1parse.c:

            added the new configuration file "ftstdlib.h" used to define
            aliases for all ISO C library functions used by the engine
            (e.g. strlen, qsort, setjmp, etc...)

            this eases the porting of FreeType 2 to exotic environments like
            XFree86 modules/extensions..

            also removed many #include <string.h>, #include <stdlib.h>, etc...
            from the engine's sources where they're not needed..

2002-04-01 14:25:28 +00:00
David Turner e459d742e6 * include/freetype/internal/ftmemory.h, and a lot of other files !!:
changed the names of memory macros. Examples:

              MEM_Set   => FT_MEM_SET
              MEM_Copy  => FT_MEM_COPY
              MEM_Move  => FT_MEM_MOVE

              ALLOC     => FT_ALLOC
              FREE      => FT_FREE
              REALLOC   = >FT_REALLOC

            FT_NEW was introduced to allocate a new object from a _typed_
            pointer..

            note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
            by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
            arguments.

            This results in _lots_ of sources being changed, but makes the
            code more generic and less error-prone..
2002-03-22 13:52:37 +00:00
David Turner 222cec8c20 * include/freetype/internal/ftdebug.h, src/base/ftdebug.c: modified
the debug sub-system initialization. trace levels can now be specified
        within the "FT2_DEBUG" environment variable. See the comments within
        "ftdebug.c" for more details

        * include/freetype/internal/fttrace.h: new file to define the trace
        levels used for debugging. it is used both to define enums and
        toggle names for FT2_DEBUG

        * src/base/ftobjs.c, src/base/ftstream.c: FT_Assert renamed to
        FT_ASSERT

        * include/freetype/internal/ftextend.h, src/base/ftextend.c,
        src/base/Jamfile, src/base/rules.mk: removing "ftextend" from the
        library, since it is now completely obsolete..
2002-02-21 11:48:48 +00:00
Werner Lemberg e274290d71 * src/smooth/ftgrays.c (gray_render_scanline): Fix bug which caused
bad rendering of thin lines (less than one pixel thick).

Cleaning up of ChangeLog.

* docs/license.txt: s/X Windows/X Window System/.

* src/raster/ftraster.c: Fix definition condition of MEM_Set().
* src/smooth/ftgrays.c (M_Y): Change value to 192.
* src/base/ftdbgmem.c (ft_mem_table_destroy): Fix printf() parameter.
Remove unused variable.
* src/cache/ftcimage.c (ftc_image_node_init,
ftc_image_node_compare): Remove unused variables.
* src/cache/ftcsbits.c (ftc_sbit_node_weight): Remove unused
variable.
* src/raster/ftraster.c (MEM_Set): Move definition down to avoid
compiler warning.
* src/autohint/ahhint.c (ah_hinter_hint_edges): Use UNUSED() to
avoid compiler warnings.
* src/pcf/pcfread.c (tableNames): Use `const'.
(pcf_read_TOC): Change counter name to avoid compiler warning.
Use `const'.
* src/pshinter/pshrec.c (ps_hints_close): Remove redundant
declaration.
* src/pshinter/pshalgo1.c (psh1_hint_table_init): Rename variables
to avoid shadowing.
* src/pshinter/pshalgo2.c (psh2_hint_table_activate_mask): Ditto.
* src/type1/t1objs.h: Remove double declarations of `T1_Size_Init()'
and `T1_Size_Done()'.
2001-12-05 01:22:05 +00:00
David Turner f2c56515f5 * src/pshinter/{pshalgo2.c, pshalgo1.c}: fixed stupid bug in sorting
routine that created nasty alignment artefacts.

        * src/pshinter/pshrec.c, tests/gview.c: debugging updates..

        * src/smooth/ftgrays.c: de-activated experimental gamme support,
        apparently, "optimal" gamma tables depend on the monitor type,
        resolution and general karma, so it's better to compute them outside
        of the rasterizer itself..
2001-11-20 01:29:34 +00:00
David Turner adf07a930c * src/smooth/ftgrays.c: adding experimental "gamma" support. This
produces smoother glyphs at small sizes for very little cost

	* src/autohint/ahglyph.c, src/autohint/ahhint.c: various fixes to
	the auto-hinter. They merely improve the output of sans-serif fonts.
	Note that there are still problems with serifed fonts and composites
	(accented characters)

	* tests/gview.c: updated the debugging glyph viewer to show the
	hints generated by the "autohint" module
2001-10-30 23:51:24 +00:00
David Turner 5a1de37e7e replaced liberal uses of "memset" by the "MEM_Set" macro call
(some platforms don't provide this ANSI function !!)

some changes to "ftsystem.c" implementations in order to use
the new memory debugger on Unix, VMS and Amiga too !!
2001-10-24 07:32:55 +00:00
David Turner 7e4b52d17b getting rid of compiler warnings 2001-10-19 09:17:49 +00:00
Werner Lemberg 80b8d77024 Fixed a bug in `glnames.py' that prevented it from generating
correct glyph names tables.  This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).

* src/tools/glnames.py (mac_standard_names): Fixed.
(t1_standard_strings): Some fixes and renamed to ...
(sid_standard_names): This.
(t1_expert_encoding): Fixed.
(the_adobe_glyph_list): Renamed to ...
(adobe_glyph_names): This.
(the_adobe_glyphs): Renamed to ...
(adobe_glyph_values): This.
(dump_mac_indices, dump_glyph_list, dump_unicode_values, main):
Updated.
* src/psnames/pstables.h: Regenerated.
* src/psnames/psmodule.c (PS_Unicode_Value): Fix offset.
Fix return value.
Use `sid_standard_table' and `ps_names_to_unicode' instead of
`t1_standard_glyphs' and `names_to_unicode'.
(PS_Macintosh_Name): Use `ps_glyph_names' instead of
`standard_glyph_names'.
(PS_Standard_Strings): Use `sid_standard_names' instead of
`t1_standard_glyphs'.
* doc/BUGS, doc/TODO: New documents.
* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.
setjmp() and longjmp() are now used for rollback (i.e. when memory
pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.

* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
too small on 16-bit systems).  <limits.h> is included to properly
get the needed data type.
(TCell, TRaster): Use it.
(TRaster): New element `jump_buffer'.
(gray_compute_cbox): Use `RAS_ARG' as the only parameter and get
`outline' from it.
(gray_record_cell): Use longjmp().
(gray_set_cell): Use gray_record_cell() for error handling.
(gray_render_line, gray_render_conic, gray_render_cubic): Simplify.
(gray_convert_glyph_inner): New function, using setjmp().
(gray_convert_glyph): Use it.


Provide a public API to manage multiple size objects for a given
FT_Face in the new header file `ftsizes.h'.

* include/freetype/ftsizes.h: New header file,
* include/freetype/internal/ftobjs.h: Use it.
Remove declarations of FT_New_Size and FT_Done_Size (moved to
ftsizes.h).
* include/freetype/config/ftheader.h (FT_SIZES_H): New macro.
* src/base/ftobjs.c (FT_Activate_Size): New function.
* src/cache/ftcmanag.c: Include ftsizes.h.
(ftc_manager_init_size, ftc_manager_flush_size): Use
FT_Activate_Size.
2001-10-10 19:56:42 +00:00
David Turner c4f622c341 * src/smooth/ftgrays: "setjmp/longjmp" is now used for rollback (i.e.
when memory pool overflow occurs), function names are now all prefixed
	with "gray_", and a new type (TArea) is defined to store area value in
	each cell (using "int" was too small on 16-bit systems)..

Werner Lemberg 1f7f0e87e5 Complete redesign of error codes. Please check ftmoderr.h for more
details.

* include/freetype/internal/cfferrs.h,
include/freetype/internal/tterrors.h,
include/freetype/internal/t1errors.h: Removed.  Replaced with files
local to the module.  All extra error codes have been moved to
`fterrors.h'.

* src/sfnt/ttpost.h: Move error codes to `fterrors.h'.

* src/autohint/aherrors.h, src/cache/ftcerror.h, src/cff/cfferrs.h,
src/cid/ciderrs.h, src/pcf/pcferror.h, src/psaux/psauxerr.h,
src/psnames/psnamerr.h, src/raster/rasterrs.h, src/sfnt/sferrors.h,
src/smooth/ftsmerrs.h, src/truetype/tterrors.h,
src/type1/t1errors.h, src/winfonts/fnterrs.h: New files defining the
error names for the module it belongs to.

* include/freetype/ftmoderr.h: New file, defining the module error
offsets.  Its structure is similar to `fterrors.h'.

* include/freetype/fterrors.h (FT_NOERRORDEF): New macro.
(FT_ERRORDEF): Redefined to use module error offsets.
All internal error codes are now public; unused error codes have
been removed, some are new.

* include/freetype/config/ftheader.h (FT_MODULE_ERRORS_H): New
macro.
* include/freetype/config/ftoption.h
(FT_CONFIG_OPTION_USE_MODULE_ERRORS): New macro.

All other source files have been updated to use the new error codes;
some already existing (internal) error codes local to a module have
been renamed to give them the same name as in the base module.

All make files have been updated to include the local error files.


* src/cid/cidtokens.h: Replaced with...
* src/cid/cidtoken.h: This file for 8+3 consistency.

* src/raster/ftraster.c: Use macros for header file names.
2001-06-06 17:30:41 +00:00
Werner Lemberg 3780273e3e * builds/unix/config.guess, builds/unix/config.sub: Updated to
latest versions from gnu.org.

* builds/compiler/gcc-dev.mk: Add `-Wno-long-long' flag.

* include/freetype/internal/ftcalc.h: Define FT_SqrtFixed()
uncoditionally.
* src/base/ftbbox.c: Include FT_INTERNAL_CALC_H.
Fix compiler warnings.
* src/base/ftcalc.c: Fix (potential) compiler warnings.

* src/base/ftcalc.c (FT_SqrtFixed): Corrected/optimized the 32-bit
fixed-point square root computation.  It is now used even with
64-bits integers, as it is _much_ faster than calling FT_Sqrt64 :-)
* src/base/ftbbox.c: Removed invalid "#include FT_BEZIER_H" line.
* src/base/ftbbox.c (BBox_Cubic_Check): Rewrote function to use
direct computations with 16.16 values instead of sub-divisions.  It
is now slower, but proves a point :-)
* src/raster/ftraster.c, src/smooth/ftgrays.c, src/base/ftbbox.c:
Fixed the bezier stack depths.
* src/base/ftcalc.c (FT_MulFix): Minor rounding fix.
* builds/beos: Added BeOS-specific files to the old build system
(no changes were necessary to support BeOS in the Jamfile though).
* ftconfig.h, ftoption.h: Updated "ftconfig.h" to detect 64-bit int
types on platforms where Autoconf is not available).  Also removed
FTCALC_USE_LONG_LONG and replaced it with
FT_CONFIG_OPTION_FORCE_INT64.
* builds/win32/freetype.dsp: Updated the Visual C++ project file.
Doesn't create a DLL yet.
* cffgload.c: Removed a compilation warning.
2001-04-26 13:34:36 +00:00
David Turner caf72cd6e5 * src/base/ftbbox.c (BBox_Cubic_Check): rewrote function to use
direct computations with 16.16 values instead of sub-divisions.
        It is now slower, but proves a point :-)

        * src/raster/ftraster.c, src/smooth/ftgrays.c, src/base/ftbbox.c :
        fixed the bezier stack depths..

        * src/base/ftcalc.c (FT_MulFix): minor rounding fix

        * builds/beos : added BeOS-specific files to the old build system
        (no changes were necessary to support BeOS in the Jamfile though)
2001-04-25 18:11:16 +00:00
David Turner 8d3a401fa8 * builds/*/*-def.mk: changed the objects directory from "obj" to "objs"
* 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..
2001-03-20 11:14:24 +00:00
Werner Lemberg 914b289f16 * src/*/*.c: Added many casts to make code more 64bit-safe. 2001-03-10 17:07:42 +00:00
David Turner 5aeaad6c39 fixed a bug reported by Graham Asher 2001-02-23 17:47:41 +00:00
Werner Lemberg 594f0c965d * *.mk: Added lots of `.PHONY' targets.
* *.mk: Implemented `platform' target to disable auto-detection.


Added support for clipped direct rendering in the smooth renderer.
This should not break binary compatibility of existing applications.
* include/freetype/fttypes.h, include/freetype/ftimage.h: Move
definition of the FT_BBox structure from the former to the latter.
* include/freetype/ftimage.h: Add `ft_raster_flag_clip' value to
FT_Raster_Flag enumeration.
Add `clip_box' element to FT_Raster_Params structure.
* src/smooth/ftgrays.c (grays_convert_glyph): Implement it.

* src/raster/ftraster.c (ft_black_render): Test for unsupported
direct rendering before testing arguments.
2000-12-20 22:09:41 +00:00
David Turner 859a18a358 support for clipped direct rendering
updated INSTALL file for Win32 case
2000-12-14 18:50:40 +00:00
Werner Lemberg 63408a1299 include/freetype/internal/internal.h: Fixed header inclusion macros
to use direct definitions.  This is the only way to do these things
in a portable way :-(  The rest of the code should follow shortly
though everything compiles now.
* builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files.

* builds/win32/detect.mk: Added support for the Intel C/C++
compiler, as well as _preliminary_ (read: doesn't work!) support for
Watcom.  Also added a new setup target.  Type "make setup list" for
a list of supported command-line compilers on Win32.

* src/base/ftdebug.c: Added dummy symbol to avoid empty file if
conditionals are off.
2000-12-13 23:44:37 +00:00
David Turner 170c0d4c0d * include/freetype/config/ft2build.h,
include/freetype/internal/internal.h: fixed header inclusion macros
	to use direct definitions. This is the only way to do these things
	in a portable way :-( The rest of the code should follow shortly
	though everything compiles now..

	* builds/compiler/intelc.mk, builds/compiler/watcom.mk,
	builds/win32/detect.mk: added support for the Intel C/C++ compiler,
	as well as _preliminary_ (read: doesn't work !!) support for Watcom.
	Also added a new setup target. Type "make setup list" for a list
	of supported command-line compilers on Win32..
2000-12-13 19:55:11 +00:00
Werner Lemberg d5c1b27d58 * include/freetype/config/ft2build.h (FT2_ROOT, FT2_CONFIG_ROOT):
Removed.  ANSI C doesn't (explicitly) allow macro expansion in
arguments using `##'.
(FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE): Use directory
names directly.  Make them configurable.  Use `##' to strip leading
and trailing spaces from arguments.

* builds/unix/ft2unix.h: Adapted.

* src/base/ftsystem.c (ft_alloc, ft_realloc, ft_free, ft_io_stream,
ft_close_stream): Use FT_CALLBACK_DEF.

* builds/unix/ftsystem.c: Use new header scheme.
(FT_Done_Memory): Use free() from FT_Memory structure.

* src/base/ftinit.c, src/base/ftmac.c: Header scheme fixes.

* include/freetype/config/ft2build.h (FT2_CONFIG_ROOT,
FT2_PUBLIC_FILE, FT2_CONFIG_FILE, FT2_INTERNAL_FILE,
FT_SOURCE_FILE): Use `##' operator to be really ANSI C compliant.
2000-12-12 22:28:12 +00:00
David Turner 19ed8afe60 - updated all source files to adhere to the new inclusion scheme
- the CFF loader now loads the encodings and charset tables
  though doesn't use them for now
2000-12-08 02:42:29 +00:00
David Turner dc26e7b77f - minor reformatting of "ftmodule.h"
- added missing "const" statements in the source code in order

David Turner ec0b2cd974 small fix:
when in direct rendering mode, the target bitmap buffer
  is not checked..

David Turner b71c6af028 fixed minor bug in the smooth renderer which forced
the span callback to be called with y == -1 and count == 0

David Turner a8194a97db - added a new function called FT_SqrtFixed to compute the
16.16 square root of a 16.16 number (this could come handy
  in a later version of the auto-hinter)

- small fixes to the smooth renderer. It used to use way too
  much line segments when drawing beziers !!

Werner Lemberg b48a6094b2 Formatting.
Moving some internal structures and constants from freetype.h to ftobjs.h.

Finally removing FT_LOAD_ANTI_ALIAS.

Cleaning up all error codes.  Only the used ones have survived :-)

Removed unused FT_MAX_GLYPH_FORMATS constant.

T2 error codes are now in the range 0x500-0x5FF (instead of `TrueDoc').

Some minor improvements of error return values.

Finally fixing error code values in ftraster and ftgrays to be compliant
with all other FT error codes.

David Turner a90663f591 vast clean-up of the sources in order to allow flat
directory compilation (by defining the FT_FLAT_COMPILE
macro at compile time..)

moved "freetype2/BUILD" to "freetype2/docs/BUILD"

Werner Lemberg bd5ae40006 Run g++ on the FreeType library. This should make the use of code in
C++ programs easier:

  Renamed FT_WordXX to FT_UIntXX.

  Changed a lot of void* to FT_Byte* if related to i/o streams -- FreeType
  always accesses streams byte-wise, so this makes sense IMHO.

  Added a lot of #ifdef __cplusplus to header files (and removed a few).

  Other minor syntax fixes (mostly casts).

  Replaced the variable `private' with `private_dict' -- `private' is
  reserved in C++.

David Turner c6a92202c2 various clean-ups:
- using FT_UNUSED instead of UNUSED
- using FT_LONG64 and FT_INT64 instead of LONG64 & INT64
- using FT_SIZEOF_INT & FT_SIZEOF_LONG instead of...

- removed the #ifdefs that used SIZEOF_INT, instead we now
  use FT_Int32 and FT_UInt32 when needed to support
  32-bits quantity correctly on 64-bits systems..

Adding copyright notices.

Removing an unnecessary file (smooth.h).

David Turner f9ca2bb58a managed to re-design entirely the API in <freetype/ftglyph.h>
It is now really the "glyph factory" that Stefan was probably
dreaming about..

fixed some recent formatting errors from Werner ;-)

cleaned up the demonstration programs from most of the
rust that they had, though I'm sure someone is going to
re-format them really soon !!

"ftstring" now uses the new ftglyph.h API, and is now
faster and smaller.. yep..
