	to the current sources, now really builds the gxvalid, gzip

	* freetype2/src/sfnt/ttload.c (sfnt_dir_check): Modified to allow a
	font to have no `head' table if tables `SING' and `META' are
	present; this is to support `SING Glyphlet'.

	`SING Glyphlet' is an extension to OpenType developed by Adobe
	primarily to facilitate adding supplemental glyphs to an OpenType
	font (with emphasis on, but not necessariy limited to, gaiji to a
	CJK font).  A SING Glyphlet Font is an OpenType font that contains
	the outline(s), either in a `glyf' or `CFF' table, for a glyph;
	`cmap', `BASE', and `GSUB' tables are present with the same format
	and functionaliy as a regular OpenType font; there are no `name',
	`head', `OS/2', and `post' tables; there are two new tables, `SING'
	which contains details about the glyphlet, and `META' which contains
	metadata.

	Further information on the SING Glyphlet format can be found at:

	  http://www.adobe.com/products/indesign/sing_gaiji.html

	* freetype2/include/freetype/ttags.h (TTAG_SING, TTAG_META): New

	* src/truetype/ttgload.c (TT_Load_Glyph): Only translate outline
	to (0,0) if bit 1 of the `head' table isn't set.  This improves
	rendering of buggy fonts.

2005-08-20  Chia I Wu  <b90201047@ntu.edu.tw>

	* src/truetype/ttdriver.c (Load_Glyph): Don't check the validity of

	valid before loading outline glyph.

	loader, when loading glyph.

	* src/truetype/ttdriver.c (tt_driver_class): Use tt_slot_init for
	glyph slot initialization.
	(Load_Glyph): Load flag dependencies are handled here.  Return error
	if size is NULL.

	* src/truetype/ttgload.c: Heavy cleanup and refactoring.
	(org_to_cur): Removed.

	No need to save/restore loader->stream before and after
	TT_Vary_Get_Glyph_Deltas now.
	(TT_LOADER_SET_PP): New macro to calculate and set the four phantom
	points.
	(load_truetype_glyph): Never set exec->glyphSize to 0.  This closes
	Savannah bug #13107.
	Forget glyph frame before calling TT_Process_Simple_Glyph.
	Use TT_LOADER_SET_PP.
	Scale all four phantom points.
	Split off some functionality to ...
	(TT_Process_Composite_Component, TT_Process_Composite_Glyph): These
	new functions.
	(TT_Load_Glyph): Set various fields of `glyph' here, not in
	load_truetype_glyph and compute_glyph_metrics.
	Split off some functionality to ...
	(load_sbit_image, tt_loader_init): These new functions.
	(compute_glyph_metrics): Call FT_Outline_Get_CBox.

	Implement a work-around for broken C preprocessor in Visual C++ (it
	has been confirmed by the MS developers that it is indeed a bug
	which won't be fixed in the very near future).

	* Jamfile (FT2_COMPONENTS): Include otvalid (again).

	* src/otvalid/otvcommn.h (OTV_NAME, OTV_FUNC): New macros.
	(OTV_NEST1, OTV_NEST2, OTV_NEST3): Use OTV_NAME and OTV_FUNC to
	avoid argument expansion by argument prescan.
	Append `Func' to all affected macros and change them to take just a
	single argument.  Example: `AttachList' is renamed to

	* src/base/ftoutln.c (FT_Outline_Embolden): Strength should be
	halved.

2005-06-16  Werner Lemberg  <wl@gnu.org>

	* include/freetype/freetype.h (FREETYPE_MINOR): Set to 2.
	(FREETYPE_PATCH): Set to 0.

	  . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
	    units.
	  . As we use the glyph's cbox to calculate the top bearing now
	    there iss no need to adjust `top'.

2005-06-15  Werner Lemberg  <wl@gnu.org>

	* src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
