to control memory debugging with FreeType. See the description of
"FT2_DEBUG_MEMORY", "FT2_ALLOC_TOTAL_MAX" and "FT2_ALLOC_COUNT_MAX"
in DEBUG.TXT
* src/cache/ftccache.c, src/cache/ftccmap.c, src/cache/ftcsbits.c,
ftlru.c: fixed the cache sub-system to correctly deal with out-of-memory
conditions.
* src/pfr/pfrobjs.c, src/pfr/pfrsbits.c: fixing compiler warnings and a
small memory leak
* src/psaux/psobjs.c (t1_reallocate_table): fixed a bug (memory leak) that
only happened when trying to resize an array would end in an OOM.
* src/smooth/ftgrays.c: removed compiler warnings / volatile bug
* src/truetype/ttobjs.c: removed segmentation fault that happened in
tight memory environments.
* include/freetype/config/ftoption.h, src/gzip/ftgzip.c: added
support for the FT_CONFIG_OPTION_SYSTEM_ZLIB option, used to specify
the use of system-wide zlib.
Note that this macro, as well as FT_CONFIG_OPTION_BYTECODE_INTERPRETER,
is not #undef-ed anymore. This allows the build system to define them
depending on the configuration (typically by adding -D flags at
compile time).
* src/sfnt/ttcmap0.c (tt_face_build_cmaps): removed compiler warnings
in optimized mode relative to the "volatile" local variables. This was
not a compiler bug after all, but the fact that a pointer to a volatile
variable is not the same than a volatile pointer to a variable :-)
the fix was to change "volatile FT_Byte* p"
into "FT_Byte* volatile p"
* src/pfr/pfrload.c, src/pfr/pfrdrivr.c, src/gzip/inftrees.c: removed
compiler warnings in optimized modes
* src/gzip/*.[hc]: modified our ZLib copy in order to prevent exporting
any zlib function names outside of the component. This prevents linking
problems on some platforms, when applications want to link FreeType
_and_ ZLib together.

* src/psaux/psobjs.c (ps_table_add): modified increment loop in
order to implement exponential behaviour
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/psaux/psobjs.c, src/type1/t1load.c, src/type1/t1tokens.h:
fixing a bug in the Type 1 loader that prevented valid font bounding
boxes to be loaded from multiple master fonts.

src/pshinter/pshalgo2.h, src/pshinter/pshalgo2.c, src/pshinter/pshalgo3.h,
src/pshinter/pshalgo3.c: Adding support for hinter-specific bit flags,
and the new FT_Set_Hint_Flags high-level API
warn about the GNU Make requirement at compile time..

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..
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..
src/type1/t1cmap.c: updating and moving the Type 1 FT_CMap support
from "src/type1" to "src/psaux" since it's going to be shared
by the Type 1 and CID font drivers..
* src/psaux/Jamfile, src/psaux/psaux.c, src/psaux/psauxmod.c,
src/psaux/rules.mk, include/freetype/internal/psaux.h: added support
for Type 1 FT_CMaps.
been touched, while keeping everything backwards-compatible..
* include/freetype/t1tables.h: re-naming structure types. This done
basically:
typedef T1_Struct_
{
} T1_Struct;
becomes:
typedef PS_StructRec_
{
} PS_StructRec, *PS_Struct;
typedef PS_StructRec T1_Struct; /* backwards-compatibility */
hence, we increase the coherency of the source code by effectuively
using the 'Rec' prefix for structure types..
src/pshinter/ahalgo2.c, src/pshinter/pshglob.h: fixed a bug where
the X and Y axis where inversed in the postscript hinter. this
caused problem when displaying on non-square surfaces..
- reallocation bug in T1_Table_Add
- increased accuracy of units per EM computation in T1 fonts
- support "+" as valid font name character (used in embedded fonts)
`cursor' and `capacity'.
* src/psaux/psobjc.c (reallocate_t1_table): Use FT_Long for second
parameter.
(PS_Table_Add): Use FT_Offset for `new_size'.
* src/base/ftsynth.c: Include ftcalc.h unconditionally.

* include/freetype/internal/psaux.h (PSAux_Interface): Updated.
* src/psaux/psobjs.c, src/psaux/psobjs.h (T1_Decrypt): Use FT_Offset
instead of FT_Int as type for `length' parameter.

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.

macro.

(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.
