David Turner 8765c71b41 * include/freetype/ftlcdfil.h, include/internal/ftobjs.h,
src/base/ftlcdfilt.c, src/smooth/ftsmooth.c: API change for
       the LCD filter, the FT_LcdFilter value is a enum describing
       which filter to apply, new values FT_LCD_FILTER_LIGHT and
       FT_LCD_FILTER_LEGACY (the latter implements the LibXft original
       algorithm which produces incredible color fringes for everything
       except very-well hinted text)

       * src/autofit/aflatin.c: various tiny improvements that drastically
       improve the handling of serif fonts and of LCD/LCD_V hinting modes.

Werner Lemberg 111b5aefca * src/base/ftcalc.c: Don't use `long long' but `FT_Int64'.

        src/type1/t1gload.c:

          this is a major patch used to drastically improve the performance
          of loading glyphs. This both speeds up loading the glypn vector
          themselves and the auto-fitter.

          note that we've started using inline assembler with GCC to
          implement FT_MulFix, given that this function is so damn
          important for the engine's performance.

          the resulting speed-up is about 25%.

    were located in 'include/freetype/cache' to the 'src/cache' directory
    instead.

    Note that these files are not used by FreeType clients, all cache
    public APIs have been already moved to include/freetype/ftcache.h,
    and the FT_CACHE_INTERNAL_XXXX_H macros all resolve to it.

    the move is to allow us to modify the internals without intereference
    from rogue clients. Note that there are no known client that accesses
    the cache internals at the moment.

Werner Lemberg 59939244ad Implement new, simplified module selection. With GNU make it is now
sufficient to modify a single file, `modules.cfg', to control the
inclusion of modules and base extension files.

This change also fixes the creation of ftmodule.h; it now depends on
`modules.cfg' and thus is rebuilt only if necessary.

Finally, a version of `ftoption.h' in OBJ_DIR is preferred over the
default location.

* modules.cfg: New file.

* builds/freetype.mk: Don't include `modules.mk'.
Include all `rules.mk' files as specified in `modules.cfg'.
(FTOPTION_FLAG, FTOPTION_H): New variables.
(FT_CFLAGS): Add macro definition for FT_CONFIG_MODULES_H.
Add FTOPTION_FLAG.
($(FT_INIT_OBJ)): Don't use FT_MODULE_LIST.
(CONFIG_H): Add FTMODULE_H and FTOPTION_H.
(INCLUDES): Add DEVEL_DIR.
(INCLUDE_FLAGS, FTSYS_SRC, FTSYS_OBJ, FTDEBUG_SRC, FTDEBUG_OBJ,
OBJ_M, OBJ_S): Use `:=', not `='.
(remove_ftmodule_h): New phony target to delete `ftmodule.h'.
(distclean): Add remove_ftmodule_h.

* builds/modules.mk: (MODULE_LIST): Removed.
(make_module_list, clean_module_list): Replace targets
with...
(FTMODULE_H_INIT, FTMODULE_H_CREATE, FTMODULE_H_DONE): New
variables.  Reason for the change is that it is not possible to have
a phony prerequisite which is run only if the target file must be
rebuilt (phony prerequisites act like subroutines and are *always*
executed).  We only want to rebuild `ftmodule.h' if `module.cfg' is
changed.
Update all callers.
($FTMODULE_H)): Rule to create `ftmodule.h', depending on
`modules.cfg'.

* builds/toplevel.mk: Rewrite and simplify module handling.
(MODULES_CFG, FTMODULE_H): New variables.
Include MODULES_CFG.
(MODULES): New variable to include all `module.mk' and `rules.mk'
files.  We no longer use make's `wildcard' function for this.

* Makefile (USE_MODULES): Remove.  Update all users.
(OBJ_DIR): Define it here.

* src/*/module.mk: Change

    make_module_list: foo
    foo: ...

to

    FTMODULE_H_COMMANDS += FOO
    define FOO
    ...
    endef

in all files.  `FTMODULE_H_COMMANDS' is used in `FTMODULE_H_CREATE'.

* src/base/rules.mk (BASE_EXT_SRC): Use BASE_EXTENSIONS.

* builds/unix/detect.mk (setup): Always execute `configure' script.
(have_mk): Rename to...
(have_Makefile): This.
Don't use `strip' function.

* builds/unix/unix.mk: Include `install.mk' only if BUILD_PROJECT is
defined.
(have_mk): Don't use `strip' function.
Test for unix-def.mk in OBJ_DIR, not BUILD_DIR (and invert the test
accordingly).

* builds/unix/install.mk (install, uninstall): Handle `ftmodule.h'.

* builds/os2/os2-dev.mk, builds/unix/unix-dev.mk,
builds/win32/w32-bccd.mk, builds/win32/w32-dev.mk: Don't define
BUILD_DIR but DEVEL_DIR for development header files.

* builds/ansi/ansi-def.mk (TOP_DIR, OBJ_DIR),
builds/beos/beos-def.mk (TOP_DIR, OBJ_DIR), builds/unix/unix-def.in
(TOP_DIR, OBJ_DIR): Removed.  Defined elsewhere.

* builds/dos/dos-def.mk (OBJ_DIR), builds/os2/os2-def.mk (OBJ_DIR),
builds/win32/win32-def.mk (OBJ_DIR): Removed.  Defined elsewhere.

* builds/unix/unixddef.mk: Don't define BUILD_DIR but DEVEL_DIR for
development header files.
Don't define PLATFORM.

* configure: Copy `modules.cfg' to builddir if builddir != srcdir.
Update snippet taken from autoconf's m4sh.m4 to current CVS version.
Be more verbose.

* include/freetype/config/ftmodule.h: Add comments -- this file is
no longer used if FreeType is built with GNU make.

* docs/CHANGES, docs/CUSTOMIZE, docs/INSTALL, docs/INSTALL.ANY,
docs/INSTALL.GNU, docs/INSTALL.UNX: Document new build mechanism.
Other minor updates.

* modules.txt: Removed.  Contents included in `modules.cfg'.


* include/freetype/internal/ftmemory.h (FT_QAlloc_Debug,
FT_Free_Debug) [FT_STRICT_ALIASING]: Fix typos.

* src/base/ftdbgmem.c (FT_Alloc_Debug, FT_Realloc_Debug,
FT_QAlloc_Debug, FT_QRealloc_Debug, FT_Free_Debug)
[FT_STRICT_ALIASING]: Implement.

Werner Lemberg f6a25503c5 * devel/ftoption.h: Synchronize with
include/freetype/config/ftoption.h.

* src/autofit/module.mk (add_autofit_module), src/bdf/module.mk
(add_bdf_module), src/type42/module.mk (add_type42_driver): Fix
whitespace.

* src/smooth/module.mk (add_smooth_renderer): Add lcd and lcdv
renderer classes.

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!
2006-01-27 12:11:22 +00:00
Werner Lemberg b36bf52795 * src/autofit/afloader.c (af_loader_load_g): Move AF_USE_WARPER up

shadowing variable declarations.
Fix warning parameters and replace printf with AF_LOG.
(af_warper_compute): Remove unused variable.

    adding experimental implementation of "warp hinting" (new hinting
    algorithm for gray-level and LCD rendering). It is disabled by default,
    you need to #define AF_USE_WARPER in aftypes.h to enable it.

David Turner 5b5f382b7d * src/autofit/aflatin.c, src/autofit/afhints.c: changed the

        horizontal hinting. This is an experimental effort to integrate
        David Chester's latest patch without fucking the other hinting
        modes as well.

        Note that this doesn't force auto-hinting for all fonts however.
