f89396cb	2014-12-04T06:17:26	[cff] Modify an FT_ASSERT. * src/cff/cf2hints.c (cf2_hintmap_map): After the fix for Savannah bug #43661, the test font `...aspartam.otf' still triggers an FT_ASSERT. Since hintmap still works with count==0, ... (cf2_glyphpath_lineTo, cf2_glyphpath_curveTo): ... add that term to suppress the assert.
2cdc4562	2014-12-04T06:10:16	[cff] Fix Savannah bug #43661. * src/cff/cf2intrp.c (cf2_interpT2CharString) <cf2_cmdHSTEM, cf2_cmdVSTEM, cf2_cmdHINTMASK>: Don't append to stem arrays after hintmask is constructed. * src/cff/cf2hints.c (cf2_hintmap_build): Add defensive code to avoid reading past end of hintmask.

a632b5f4	2014-12-03T19:30:44	[autofit] Better fix for conversion specifiers in debug messages. Using `%ld' for pointer differences causes warnings on 32bit platforms. The correct type would be (the relatively new) `%td', however, this is missing on some important platforms. This patch improves the change from 2014-11-28. * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our pointer differences are always sufficiently small. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.
16188ebf	2014-12-03T10:18:34	FT_Sfnt_Tag: s/ft_sfnt_xxx/FT_SFNT_XXX/ for orthogonality. All public FreeType enumeration and flag values are uppercase... * include/tttables.h (FT_Sfnt_Tag): Implement it. For backwards compatilibity, retain the old values as macros. * src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c (get_sfnt_table): Updated.
de43ace7	2014-12-02T23:06:04	* include/*: Improve structure of documentation. . Add and update many `<Order>' tags. . Apply various documentation fixes. . Remove details to deprecated (or never implemented) data.
ca1f5cc7	2014-12-02T22:49:25	[docmaker] Always handle `<Order>' section elements. Previously, those elements were handled only for sections present in a `<Sections>' chapter element. * src/tools/docmaker/content.py (ContentProcessor::finish): Implement it.
ef6a3523	2014-12-02T21:16:59	[docmaker] Properly handle empty rows in Synopsis. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit ` ' for empty fields.
0e96f050	2014-12-02T11:08:31	[docmaker] Thinko. * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): Emit `/empty/' string for first element also.
102d4a76	2014-12-02T10:27:40	[docmaker] Honour empty lines in `<Order>' section element. This greatly improves the readability of the `Synopsis' links. * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): Insert string `/empty/' between items. * src/tools/docmaker/formatter.py (Formatter::section_dump): Make it robust against nonexistent keys. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Emit empty <td> elements for `/empty/'.
2af25ac0	2014-12-02T08:38:57	[docmaker] Ensure Python 3 compatibility. * src/tools/docmaker/content.py (ContentProcessor::set_section, ContentProcessor::finish): Replace `has_key' function with `in' keyword. * src/tools/docmaker/formatter.py (Formatter::__init__): Replace sorting function with a key generator. (Formatter::add_identifier): Replace `has_key' function with `in' keyword. * src/tools/docmaker/tohtml.py (HtmlFormatter::html_source_quote): Replace `has_key' function with `in' keyword. (HtmlFormatter::index_exit, HtmlFormatter::section_enter): Use integer division. s/<>/>/. * src/tools/docmaker/utils.py: Import `itertools'. (index_sort): Replaced by... (index_key): ... this new key generator (doing exactly the same).
80bfeb1c	2014-12-01T10:07:52	[docmaker] Don't output a block multiple times. This bug was hidden by not processing all lines of `<Order>' blocks. * src/tools/docmaker/formatter.py (Formatter::section_dump): Filter out field names.
0dbad763	2014-12-01T08:44:48	[docmaker] Use field values as HTML link targets where possible. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_block_url): Accept second, optional argument to specify a name. (HtmlFormatter::html_source_quote): Link to field ID if possible. (HtmlFormatter::print_html_field_list): Emit `id' attribute.
785b1d08	2014-11-30T22:16:34	[docmaker] Allow empty lines in `<Order>' blocks. Before this patch, the suggested order of entries stopped at the first empty line. Obviously, nobody noticed that this problem caused a much reduced set of links in the `Synopsis' sections; in particular, the `<Order>' blocks contain a lot of entries that wouldn't be listed otherwise... * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): New function to iterate over all items. (DocSection::process): Use it.
16b3e620	2014-11-30T20:58:27	* src/tools/docmaker/sources.py (column) [Format 2]: Fix regexp. After the single asterisk there must be no other immediately following asterisk.

aa834ce5	2014-11-29T20:08:29	[docmaker] Provide higher-level markup and simplify HTML. * src/tools/docmaker/tohtml.py: Instead of using extraneous `<div>' elements, use CSS descendants (of class `section') to format the data. Also remove reduntant <p> and <br> elements, replacing them with proper CSS. Globally reduce page width to 75%. (block_header): Rename <div> class to `section'.
3bb97023	2014-11-29T16:12:37	[docmaker] Add `top' links after blocks. * src/tools/docmaker/tohtml.py (block_footer_middle): Implement it.
a31f9715	2014-11-29T07:18:44	* src/tools/docmaker/tohtml.py: Improve CSS for fields. Make fields align horizotnally relative to full line width.
8f795118	2014-11-29T06:49:15	* src/tools/docmaker/tohtml.py: Fix index and TOC templates. This thinko was introduced 2014-11-27.
ba1ba0ca	2014-11-28T22:04:14	[docmaker] Format field lists with CSS. This also simplifies the inserted HTML code. * src/tools/docmaker/tohtml.py (HtmlFormatter::print_html_field_list): Do it.
348fffa8	2014-11-28T16:05:59	Fix compiler warning to the comparison between signed and unsigned variable. * src/pfr/pfrsbit.c (pfr_slot_load_bitmap): Fix the comparison between `ypos + ysize' and FT_INT_{MAX,MIN}.
46d4dc86	2014-11-28T05:49:56	[docmaker] Replace empty `<td>' with CSS.. * src/tools/docmaker/tohtml.py (HtmlFormatter::section_enter): Do it.
984e0717	2014-11-28T05:33:58	[docmaker] Replace some `<table>' tags with `<h4>' and `<div>'. * src/tools/docmaker/tohtml.py (marker_): Use `<h4>'. (source_): Use `<div>'. (HtmlFormatter::block_enter): s/<h4>/<h3>/.
9ee6a0a0	2014-11-28T11:14:18	Fix compiler warning to conversion specifiers in debug messages. * src/autofit/afhints.c (af_glyph_hints_dump_points): Add length modifier to dump long integers. (af_glyph_hints_dump_segments, af_glyph_hints_dump_edges): Ditto.

26d699ed	2014-11-27T19:22:52	* src/tools/docmaker/tohtml.py: Remove remaining `width' attributes. For `Index' and `TOC' links, we now simply use the `text-align' CSS property of `<td>' to enforce flush-left and flush-right, eliminating the hack with an empty, full-width `<td>' element inbetween. The change also enforces the same (smaller) size for all index and TOC links.
1b12f5d1	2014-11-28T01:22:26	* src/cff/cf2font.c: Include `ftcalc.h' to use FT_MSB(), cf2font.c could not find it under `make multi' build.
2676e07a	2014-11-28T00:58:25	* src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove unrequired negative value check for `width' and `height'.
dd3fee07	2014-11-27T13:20:52	* src/tools/docmaker/tohtml.py: More HTML table refactoring. Replace some `<table>' tags with `<div>' to simplify structure. Move `bgcolor' attribute to CSS. Replace most `width' attributes with CSS. The remaining instances (providing a similar effect as LaTeX's `\hfill' command) are removed in a later patch.
a5ad26af	2014-11-27T10:52:24	* src/tools/docmaker/tohtml.py: Replace <font> with CSS.
ba67c619	2014-11-27T10:51:49	* src/tools/docmaker/tohtml.py: Center <table> with CSS.

dbb93157	2014-11-27T07:20:48	Use better way to disable creation of .pyc files for `make refdoc'. Python 2.6 was released in 2008... * builds/freetype.mk (refdoc): Use python's `-B' option. * builds/detect.mk (std_setup, dos_setup): Mention required python version for `refdoc' target.
e8a5c33e	2014-11-27T06:48:37	* src/tools/docmaker/sources.py (re_bold, re_italic): Use non-grouping parentheses. * src/tools/docmaker/tohtml.py (HtmlFormatter::make_html_word): Updated.
3d167cbe	2014-11-27T05:19:41	* src/base/ftobjs.c (FT_Get_Glyph_Name): Fix compiler warning. Introdruced in previous change. Reported by Alexei.
f34f1925	2014-11-26T21:59:21	* src/: Add checks for parameters of API functions where missing. `API functions' are functions tagged with `FT_EXPORT_DEF'. Besides trivial fixes, the following changes are included, too. src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set error code if no service is available. * src/base/ftinit.c (FT_Done_FreeType): Change return value for invalid `library' parameter to `Invalid_Library_Handle'. * src/base/ftobjs.c (FT_New_Size): Change return value for invalid `asize' parameter to `Invalid_Argument'. * src/base/ftoutln.c (FT_Outline_Copy): Change return value for invalid `source' and `target' parameters to `Invalid_Outline'.

b24e8ba2	2014-11-25T08:30:49	[Savannah bug #43682] Add/remove `void' casts to some functions. We use a cast to indicate that we intentionally ignore a function's return value. However, this doesn't apply to API functions where errors can only happen for trivially invalid input. * src/base/ftstroke.c (FT_Glyph_Stroke, FT_Glyph_StrokeBorder), src/base/ftsynth.c (FT_GlyphSlot_Embolden), src/cff/cffgload.c (cff_slot_load), src/pfr/pfrdrivr.c (pfr_get_kerning), src/type1/t1load.c (parse_encoding), src/type42/t42parse.c (t42_parse_encoding): Do it.
ef439fd2	2014-11-25T08:14:15	[Savannah bug #43682] Change some signatures to `void' return type. * include/internal/pshints.h (PSH_Globals_SetScaleFunc), include/internal/sfnt.h (TT_Get_Metrics_Func), src/pshinter/pshglob.c (psh_globals_set_scale), src/pshinter/pshrec.c (ps_hints_init), src/sfnt/ttmtx.c (tt_face_get_metrics), src/truetype/ttinterp.c (TT_Goto_CodeRange, TT_Set_CodeRange, TT_Clear_CodeRange, TT_Done_Context, TT_Save_Context): Do it. * src/pshinter/pshglob.h, src/pshinter/pshrec.h, src/sfnt/ttmtx.h, src/truetype/ttgload.c (TT_Hint_Glyph), src/truetype/ttinterp.c (TT_Run_Context), src/truetype/ttinterp.h, src/truetype/ttobjs.c (tt_size_run_fpgm, tt_size_run_prep): Updated.
6889f7b7	2014-11-24T17:16:08	Remove all code related to FT_MAX_CHARMAP_CACHEABLE. This is no longer used. * src/base/ftobjs.c, src/cache/ftccmap.c, src/cff/cffobjs.c, src/sfnt/ttcmap.c: Do it.
f0292bb9	2014-11-24T10:51:21	[sfnt] Fix Savannah bug #43680. This adds an additional constraint to make the fix from 2013-01-25 really work. * src/sfnt/ttsbit.c (tt_sbit_decoder_load_image) <index_format==4>: Check `p' before `num_glyphs'.
eca0f067	2014-11-24T10:22:08	[truetype] Fix Savannah bug #43679. * src/truetype/ttpload.c (tt_face_load_hdmx): Check minimum size of `record_size'.
96341dc3	2014-11-24T09:53:07	[cff, pfr, psaux, winfonts] Fix Savannah bug #43676. Don't cast cmap init function pointers to an incompatible type. Without this patch, the number of parameters between declaration and the real signature differs. Calling such a function results in undefined behavior. ISO/IEC 9899:TC3 (Committee Draft September 7, 2007) 6.5.2.2 Function calls 9 If the function is defined with a type that is not compatible with the type (of the expression) pointed to by the expression that denotes the called function, the behavior is undefined. On certain platforms (c -> js with emscripten) this causes termination of execution or invalid calls because in the emscripten implementation, function pointers of different types are stored in different pointer arrays. Incorrect pointer type here results in indexing of an incorrect array. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_unicode_init), src/pfr/pfrcmap.c (pfr_cmap_init), src/psaux/t1cmap.c t1_cmap_standard_init, t1_cmap_expert_init, t1_cmap_custom_init, t1_cmap_unicode_init), src/winfonts/winfnt.c (fnt_cmap_init): Fix signature.

73be9f9a	2014-11-24T07:30:05	[type1, type42] Another fix for Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Add another boundary testing.
a7a4207d	2014-11-24T06:44:45	[docmaker] Formatting, copyright, improved documentation. * src/tools/docmaker/*: No code changes besides trivial modifications.
af834617	2014-11-22T13:29:10	[bdf] Fix Savannah bug #43660. * src/bdf/bdflib.c (_bdf_parse_glyphs) <"ENDFONT">: Check `_BDF_GLYPH_BITS'.
42fcd669	2014-11-22T12:44:33	[type42] Allow only embedded TrueType fonts. This is a follow-up to Savannah bug #43659. * src/type42/t42objs.c (T42_Face_Init): Exclusively use the `truetype' font driver for loading the font contained in the `sfnts' array.
3788187e	2014-11-22T10:46:47	[type42] Fix Savannah bug #43659. * src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'. * src/type42/t42parse.c (t42_parse_sfnts): Always set `face->ttf_size' directly. This ensures a correct stream size in the call to `FT_Open_Face', which follows after parsing, even for buggy input data. Fix error messages.
5f201ab5	2014-11-22T09:16:39	[cff] Fix Savannah bug #43658. * src/cff/cf2ft.c (cf2_builder_lineTo, cf2_builder_cubeTo): Handle return values of point allocation routines.
9bd20b73	2014-11-22T06:24:45	[sfnt] Fix Savannah bug #43656. * src/sfnt/ttcmap.c (tt_cmap4_validate): Fix order of validity tests.
dd89710f	2014-11-21T22:19:28	[type1, type42] Fix Savannah bug #43655. * src/type1/t1load.c (parse_charstrings), src/type42/t42parse.c (t42_parse_charstrings): Fix boundary testing.
b1fc00d5	2014-11-21T12:06:40	* src/pcf/pcfread.c (pcf_get_metrics): Sanitize invalid metrics.
9154dab8	2014-11-21T08:03:51	[ftlcdfil] Obey flow direction. * src/base/ftlcdfil.c (_ft_lcd_filter_fir, _ft_lcd_filter_legacy): Handle `up' flow.
644d6fab	2014-11-21T07:28:50	* src/base/ftbitmap.c (FT_Bitmap_Convert): Improve. This commit completes argument checks and adds support for different flow directions.
6de76174	2014-11-21T06:05:49	* src/base/ftbitmap.c (FT_Bitmap_Copy): Improve. This commit adds argument checks and support for different flow directions.
1e6e1b83	2014-11-20T21:07:56	* src/base/ftbitmap.c (FT_Bitmap_New): Check argument.
b3500af7	2014-11-19T21:28:21	Change some fields in `FT_Bitmap' to unsigned type. This doesn't break ABI. * include/ftimage.h (FT_Bitmap): Make `rows', `width', `num_grays', `pixel_mode', and `palette_mode' unsigned types. * src/base/ftbitmap.c: Updated. (FT_Bitmap_Copy): Fix casts. * src/cache/ftcsbits.c, src/raster/ftraster.c, src/sfnt/pngshim.c: Updated.
df485774	2014-11-19T21:21:23	Make `FT_Bitmap_Convert' correctly handle negative `pitch' values. * src/base/ftbitmap.c (FT_Bitmap_Convert): Always use positive value for the pitch while copying data. Correctly set pitch sign in target bitmap.
d6061212	2014-11-19T21:13:23	Minor code improvement in `FT_Bitmap_Embolden'. * src/base/ftbitmap.c (FT_Bitmap_Embolden) <FT_PIXEL_MODE_GRAY[24]>: Fix thinko.
f841ad3e	2014-11-19T21:19:06	* src/base/fttrigon.c: Use dedicated `FT_Angle' for arctan table.
a67c43e1	2014-11-19T06:46:23	Avoid compiler warnings on x86-64 for `FT_MulFix'. `FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h', but several inline implementations of it in `ftcalc.h' take `FT_Int32' arguments. This is causing compiler warnings on x86-64: If parameters of type `FT_Fixed' (= `FT_Long') are passed to the inline implementation of this function, integer values are truncated from 64bit to 32bit. * include/internal/ftcalc.h (FT_MulFix) [FT_MULFIX_ASSEMBLER]: Add casts.
54abd228	2014-11-15T09:05:22	[sfnt] Fix Savannah bug #43597. * src/sfnt/pngshim.c (Load_SBit_Png): Protect against too large bitmaps.
257c270b	2014-11-12T21:42:13	[sfnt] Fix Savannah bug #43591. * src/sfnt/ttsbit.c (tt_sbit_decoder_init): Protect against addition and multiplication overflow.
677ddf4f	2014-11-12T21:26:44	[sfnt] Fix Savannah bug #43590. * src/sfnt/ttload.c (check_table_dir, tt_face_load_font_dir): Protect against addition overflow.
f46add13	2014-11-12T21:06:08	[sfnt] Fix Savannah bug #43589. * src/sfnt/sfobjs.c (woff_open_font): Protect against addition overflow.

2e73a1b4	2014-11-09T23:22:43	[base] CORDIC improvements. The scaling between the hypotenuse and its CORDIC approximation is based on regression analysis. The smaller padding for `theta' is justifed by its maximum error of less than 6. * src/base/fttrigon.c (ft_trig_downscale): Borrow code from ./ftcalc.c (ft_multo64), change linear intercept. (ft_trig_pseudo_polarize): Decrease `theta' padding.
0e73d218	2014-11-09T01:27:38	* src/base/ftstroke.c (ft_stroker_inside): Fix border intersections. One more place to check whether `radius' is zero. Problem reported by Marco Wertz <marco.wertz@gmx.de>.
2c4832d3	2014-11-07T07:42:33	Fix Savannah bug #43535. * src/bdf/bdflib.c (_bdf_strncmp): New macro that checks one character more than `strncmp'. s/ft_strncmp/_bdf_strncmp/ everywhere.

0e2f5d51	2014-11-06T22:32:46	Fix Savannah bug #43547. * src/pcf/pcfread.c (pcf_read_TOC): Check `size' and `offset' values.
f49a100a	2014-11-06T13:30:28	* src/pcf/pcfread.c (pcf_read_TOC): Avoid memory leak.
facfc79a	2014-11-03T07:24:59	* src/truetype/ttsubpix.c (COMPATIBILITY_MODE_Rules): Updated. The previous commit deteriorates rendering of DejaVu and similar fonts; this gets compensated with this rule.
706f752b	2014-11-03T07:20:57	* src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting. Before this patch, it was impossible to ever call DELTAP[123] in subpixel hinting mode as described in the ClearType whitepaper; it only worked if in `compatibility mode'. However, compatibility mode essentially disables SHPIX, completely ruining hinting of ttfautohint output, for example. We now follow the whitepaper more closely so that DELTAP[123] instructions for touched points in the non-subpixel direction are executed.
525d4876	2014-10-31T22:12:37	[smooth] Improve code readability. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Rearrange code.
e1efe0a2	2014-10-31T00:07:14	[smooth] Reduce outline translations during rendering. * src/smooth/ftsmooth.c (ft_smooth_render_generic): Translate origin virtually by modifying cbox, actually translate outline if cumulative shift is not zero.
c7fd9356	2014-10-30T22:43:01	[smooth] Fix Savannah bug #35604 (cont'd). * src/smooth/ftsmooth.c (ft_smooth_render_generic): Remove checks and casts that became unnecessary after the variable type upgrades.

[autofit] Better fix for conversion specifiers in debug messages. Using `%ld' for pointer differences causes warnings on 32bit platforms. The correct type would be (the relatively new) `%td', however, this is missing on some important platforms. This patch improves the change from 2014-11-28. * src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our pointer differences are always sufficiently small. (af_glyph_hints_dump_points, af_glyph_hints_dump_segments, af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

2014-11-30T22:16:34

[docmaker] Allow empty lines in `<Order>' blocks. Before this patch, the suggested order of entries stopped at the first empty line. Obviously, nobody noticed that this problem caused a much reduced set of links in the `Synopsis' sections; in particular, the `<Order>' blocks contain a lot of entries that wouldn't be listed otherwise... * src/tools/docmaker/content.py (DocBlock::get_markup_words_all): New function to iterate over all items. (DocSection::process): Use it.

26d699ed

2014-11-27T19:22:52

* src/tools/docmaker/tohtml.py: Remove remaining `width' attributes. For `Index' and `TOC' links, we now simply use the `text-align' CSS property of `<td>' to enforce flush-left and flush-right, eliminating the hack with an empty, full-width `<td>' element inbetween. The change also enforces the same (smaller) size for all index and TOC links.

1b12f5d1

2014-11-28T01:22:26

[cff, pfr, psaux, winfonts] Fix Savannah bug #43676. Don't cast cmap init function pointers to an incompatible type. Without this patch, the number of parameters between declaration and the real signature differs. Calling such a function results in undefined behavior. ISO/IEC 9899:TC3 (Committee Draft September 7, 2007) 6.5.2.2 Function calls 9 If the function is defined with a type that is not compatible with the type (of the expression) pointed to by the expression that denotes the called function, the behavior is undefined. On certain platforms (c -> js with emscripten) this causes termination of execution or invalid calls because in the emscripten implementation, function pointers of different types are stored in different pointer arrays. Incorrect pointer type here results in indexing of an incorrect array. * src/cff/cffcmap.c (cff_cmap_encoding_init, cff_cmap_unicode_init), src/pfr/pfrcmap.c (pfr_cmap_init), src/psaux/t1cmap.c t1_cmap_standard_init, t1_cmap_expert_init, t1_cmap_custom_init, t1_cmap_unicode_init), src/winfonts/winfnt.c (fnt_cmap_init): Fix signature.

[type42] Allow only embedded TrueType fonts. This is a follow-up to Savannah bug #43659. * src/type42/t42objs.c (T42_Face_Init): Exclusively use the `truetype' font driver for loading the font contained in the `sfnts' array.

[type42] Fix Savannah bug #43659. * src/type42/t42objs.c (T42_Open_Face): Initialize `face->ttf_size'. * src/type42/t42parse.c (t42_parse_sfnts): Always set `face->ttf_size' directly. This ensures a correct stream size in the call to `FT_Open_Face', which follows after parsing, even for buggy input data. Fix error messages.

2014-11-19T06:46:23

Avoid compiler warnings on x86-64 for `FT_MulFix'. `FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h', but several inline implementations of it in `ftcalc.h' take `FT_Int32' arguments. This is causing compiler warnings on x86-64: If parameters of type `FT_Fixed' (= `FT_Long') are passed to the inline implementation of this function, integer values are truncated from 64bit to 32bit. * include/internal/ftcalc.h (FT_MulFix) [FT_MULFIX_ASSEMBLER]: Add casts.

[base] CORDIC improvements. The scaling between the hypotenuse and its CORDIC approximation is based on regression analysis. The smaller padding for `theta' is justifed by its maximum error of less than 6. * src/base/fttrigon.c (ft_trig_downscale): Borrow code from ./ftcalc.c (ft_multo64), change linear intercept. (ft_trig_pseudo_polarize): Decrease `theta' padding.

* src/truetype/ttinterp.c (Ins_DELTAP): Fix subpixel hinting. Before this patch, it was impossible to ever call DELTAP[123] in subpixel hinting mode as described in the ClearType whitepaper; it only worked if in `compatibility mode'. However, compatibility mode essentially disables SHPIX, completely ruining hinting of ttfautohint output, for example. We now follow the whitepaper more closely so that DELTAP[123] instructions for touched points in the non-subpixel direction are executed.
