`svgrender.h' -> `otsvg.h'
`FT_SVG_RENDER_H' -> `FT_OTSVG_H'
Since `svgrender.h' contains just the hooks and the SVG document
structure it's probably just better to name it something general
like `otsvg.h'.
Inside the SVG Document List, four fields exist. It's
better to create a struct to hold at one place instead
of 4 variables. Also created `compare_svg_doc' which
will be helpful in writing binary search later.
A field `units_per_EM' is added to `FT_SVG_DocumentRec' and
`FT_SvgGlyphRec'. This is needed because the renderer needs this
info to properly scale the SVGs if the viewbox width and height
differ from `face->units_per_EM'. Face object can't be accessed
because of the restrictions put by `FT_Glyph_To_Bitmap' thus this
has to be provided separately just like `metrics'.
* include/freetype/internal/ftobjs.h: Create a new flag named
`FT_GLYPH_OWN_GZIP_SVG' to indicate that `svg_document' in
`slot->other' is GZIP compressed and has to be freed later.
* src/base/ftglyph.c: Minor styling.
* src/base/ftobjs.c: Add code to free memory that was previously
allocated for storing GZIP compressed SVG documents.
* src/sfnt/ttsvg.c: Set the `FT_GLYPH_OWN_GZIP_SVG' flag if the
document is GZIP compressed.
* include/freetype/freetype.h: Add `FT_FACE_FLAG_SVG' to indicate
the presence of an SVG table in the face.
* src/base/ftobjs.c (ft_glyphslot_init): Allocate memory for
`FT_SVG_Document' in `slot->other' if an SVG table exists in the
face.
(ft_glyphslot_clear): Clear `slot->other' only if the font doesn't
have an SVG table.
(ft_glyphslot_done): Free the memory at `slot->other' if the face
has an SVG table.
* src/base/ttsvg.c (tt_face_load_svg): Set `FT_FACE_FLAG_SVG'.
(tt_face_load_svg_doc): Don't allocate the memory.
* src/base/ftobjs.c (FT_Load_Glyph): Use the recrusive call with
`FT_LOAD_NO_SCALE' so that the loaded data is unscaled.
* src/base/ftobjs.c (FT_Render_Glyph_Internal): Change the format
to bitmap once an SVG glyph is successfully rendered.
* src/sfnt/ttsvg.c (tt_face_load_svg_doc): Make sure metrics are
grabbed. Scale `horiAdvance' and `vertAdvance' properly and
convert them to 26.6 format.

* src/autofit/afcjk.c (af_cjk_hints_compute_edges): Catch a corner
case where `edge->first' could be NULL.
* src/pfr/pfrobjs.c (pfr_slot_load): Remove unnecessary test of
`size'.
* src/raster/ftraster.c (Draw_Sweep): Catch a corner case where
`draw_right' might be NULL.
* src/sfnt/ttmtx.c (tt_face_get_metrics): Fix limit test for
`aadvance'.
Ensure `abearing' always hold a meaningful result.
* src/truetype/ttgload.c (load_truetype_glyph): Ensure `subglyph' is
not NULL before accessing it.
* src/truetype/ttgxvar.c (TT_Set_Named_Instance): Remove unnecessary
test of `namedstyle'.
* src/type42/t42parse.c (t42_parser_done): Ensure
`parser->root.funcs.done' is not NULL before accessing it.
If the OS/2 table exists and fsSelection bit 7 (USE_TYPO_METRICS) is set,
use the sTypo* set of values to compute the FT_Face's ascender, descender
and height. Otherwise, fall back to old behavior.
* src/sfnt/sfobjs.c (sfnt_load_face): Implement.
It's been more than 2^31 seconds since 1904.
* include/freetype/tttables.h (TT_Header): Change field types.
* src/sfnt/ttload.c (tt_face_load_generic_header): Updated.
This is a follow-up to the previous commit.
* src/cff/cffobjs.c (cff_face_init), src/sfnt/sfobjs.c
(sfnt_load_face), src/type1/t1objs.c (T1_Face_Init),
src/type42/t42objs.c (T42_Face_Init): Implement it.
* src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks.
(get_win_string, get_apple_string): Return NULL when the PostScript
font name characters is not according to specification.
(get_win_string): Make trace output work if the high byte if
non-zero.
(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
Win PS name (when there is also an Apple PS name); change this into
a fallback to Apple PS name in case the Win PS name is invalid.
