6b19e095be * src/truetype/ttpload.c (tt_face_load_loca): Handle buggy fonts
where num_locations < num_glyphs.  Problem reported by Ding Li.

ce8853af81 * src/truetype/ttinterp. (Ins_SCANTYPE): Don't check rendering mode.
* src/raster/ftraster.c (Render_Glyph, Render_Gray_Glyph,
Draw_Sweep): No-dropout mode is value 2, not value 0.
(Draw_Sweep): Really skip dropout handling for no-dropout mode.

5df5dbb722 Enable access to the various dropout rules of the B&W rasterizer.
Pass dropout rules from the TT bytecode interpreter to the
rasterizer; temporarily this is enabled only if
`USE_SCAN_CONVERSION_RULES' is defined.

* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.

* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
OpenType specification.
Fix mode 4 computation.
(Render_Glyph, Render_Gray_Glyph): Handle new outline flags.

* src/truetype/ttgload.c (TT_Load_Glyph)
[USE_SCAN_CONVERSION_RULES]: Convert scan conversion mode to
FT_OUTLINE_XXX flags.

* src/truetype/ttinterp.c (Ins_SCANCTRL): Enable ppem check.

7cb9ec0f1c * src/type1/t1parse.h (T1_ParserRec): Make `base_len' and
`private_len' unsigned.

* src/type1/t1parse.c (read_pfb_tag): Make `asize' unsigned and read
it as such.
(T1_New_Parser, T1_Get_Private_Dict): Make `size' unsigned.


* src/base/ftstream.c (FT_Stream_Skip): Reject negative values.


* src/type1/t1load.c (parse_blend_design_positions): Check `n_axis'
for sane value.
Fix typo.


* src/psaux/psobjs.c (ps_table_add): Check `idx' correctly.


* src/truetype/ttinterp (Ins_SHC): Use BOUNDS() to check
`last_point'.


* src/sfnt/ttload.c (tt_face_load_max_profile): Limit
`maxTwilightPoints'.

ffa496574a * src/truetype/ttgload.c (load_truetype_glyph): Move initialization
of the graphics state for subglyphs to...
(TT_Hint_Glyph): This function.
Hinting instructions for a composite glyph apparently refer to the
just hinted subglyphs, not the unhinted, unscaled outline.  This
seems to fix Savannah bugs #20973 and (at least partially) #23310.

ft_wgl_extra_glyph_name_offsets): New arrays.
(ps_check_wgl_name, ps_check_wgl_unicode): New functions.

bf391cb858 * src/truetype/ttgload.c (load_truetype_glyph): Handle the case
where the number of contours in a simple glyph is zero (and which
does contain an entry in the `glyf' table).  This fixes Savannah bug
#21990.

bd7e1c3ce0 Pass options from one configure script to another as-is (not
expanded).  This is needed for options like
--includedir='${prefix}/include'.

* builds/unix/detect.mk, configure: Prevent argument expansion in
call to the (real) `configure' script.



* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
TT_USE_BYTECODE_INTERPRETER isn't defined.



There exist CFFs which contain opcodes for the Type 1 operators
`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
However, it doesn't harm to support them.

* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
`cff_op_closepath.'
(cff_argument_counts): Ditto.

(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
and 13 (hsbw) which are invalid in Type 2 charstrings.

3033f4366b * src/truetype/ttgload.c (load_truetype_glyph): Always allow a
recursion depth of 1.  This was the maximum value in TrueType 1.0,
and some older fonts don't set this field correctly.

* src/gxvalid/gxvmort1.c
(gxv_mort_subtable_type1_substTable_validate): Fix tracing message.
