	earlier one.

	(FT_Get_Charmap_Index): When a requested charmap is found

	after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap

	index.



2010-07-04  Werner Lemberg  <wl@gnu.org>



	TrueType hinting is no longer patented.



	* include/freetype/config/ftoption.h, devel/ftoption.h

2010-07-02  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>



	Additional fix for Savannah bug #30306.



	* src/base/ftobjs.c (Mac_Read_POST_Resource): If the type of the

	POST fragment is 0, the segment is completely ignored.  The declared

	length of the segment is not cared at all.  According to Adobe

	Technical Note 5040, type 0 segment is a comment only and should not

	be loaded for the interpreter.  Reported by Robert Święcki.



2010-07-01  Werner Lemberg  <wl@gnu.org>

	int' to avoid integer overflow.



	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Use smaller

	threshold values for `width' and `height'.  This is not directly

	related to the bug fix but makes sense anyway.



2010-07-01  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>



	Initial fix for Savannah bug #30306.



	* src/base/ftobjs.c (Mac_Read_POST_Resource): Check `rlen', the

	length of fragment declared in the POST fragment header, and prevent

	an underflow in length calculation.  Some fonts set the length to

	zero in spite of the existence of a following 16bit `type'. 

	Reported by Robert Święcki.



2010-07-01  suzuki toshiya  <mpsuzuki@hiroshima-u.ac.jp>

2010-06-24  Werner Lemberg  <wl@gnu.org>

	Fix Savannah bug #30168.



	* src/pfr/pfrgload.c (pfr_glyph_load_compound): Limit the number of

	* src/pshinter/pshalgo.c (psh_glyph_find_strong_points): Assure that

	`end_point' is not larger than `glyph->num_points'.

2010-05-10  Ken Sharp  <ken.sharp@artifex.com>



	Fix Savannah bug #29846.



	Previously we discovered fonts which used `setcurrentpoint' to set

	the initial point of a contour to 0,0.  This caused FreeType to

	raise an error, because the `setcurrentpoint' operator is only

	supposed to be used with the results from an OtherSubr subroutine.



	This was fixed by simply ignoring the error and carrying on.



	Now we have found a font which uses setcurrentpoint to actually

	establish a non-zero point for a contour during the course of a

	glyph program.  FWIW, these files may be produced by an application

	called `Intaglio' on the Mac, when converting TrueType fonts to

	Type 1.



	The fix allows the new invalid behaviour, the old invalid behaviour

	and real proper usage of the operator to work the same way as Adobe

	interpreters apparently do.



	(t1_decoder_parse_charstrings): Make `setcurrentpoint' use the top

	two elements of the stack to establish unconditionally the current x

	and y coordinates.



	Make the `flex' subroutine handling (OtherSubr 0) put the current

	x,y coordinates onto the stack, instead of two dummy uninitialised

	values.
