[sfnt] Speed up `sbix' lookup.
This also fixes a bug introduced in 2016-10-01 which prevents
display of embedded bitmap fonts that use the `sbix' format.
* src/sfnt/ttsbit.c (tt_face_load_sbit): Store `sbix' size and
offset also in `ebdt_size' and `ebdt_start', respectively. This
makes the test for an embedded bitmap data table succeed for this
format.
(tt_face_load_strike_metrics) <TT_SBIT_TABLE_TYPE_SBIX>: Use
`ebdt_size' and `ebdt_start'
(tt_face_load_sbix_image): Ditto.

Introduce a way of quickly retrieving (embedded) bitmap metrics.
`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
until the user calls `FT_Render_Glyph'. However, it always
allocates memory for bitmaps and copies or decodes the contents of a
bitmap glyph, which can be quite slow for PNG data.
* include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
macro.
* src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
FT_LOAD_BITMAP_METRICS_ONLY is used.
* src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap,
tt_sbit_decoder_load_bitmap): Add argument to control allocation of
the glyph slot.
(tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound,
tt_face_load_sbit_image): Updated.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if
`FT_LOAD_BITMAP_METRICS_ONLY' is set.
* src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add

[pcf] Enrich family name with foundry name and glyph width info.
This is a very old patch from openSuSE (from 2006, submitted to
FreeType in 2011) that I forgot to apply.
https://build.opensuse.org/package/view_file/openSUSE:Factory/freetype2/freetype2-bitmap-foundry.patch
Prepend the foundry name plus a space to the family name. There are
many fonts just called `Fixed' which look completely different, and
which have nothing to do with each other. When selecting `Fixed' in
KDE or Gnome one gets results that appear rather random, the style
changes often if one changes the size and one cannot select some
fonts at all.
We also check whether we have `wide' characters; all put together,
we get family names like `Sony Fixed' or `Misc Fixed Wide'.
* src/pcf/pcfread.c (pcf_load_font): Implement it.
* docs/CHANGES: Document it.

Without this patch, a loca sequence like `0 100000 0 100000 ...',

FreeType handle the whole `glyf' table as a single glyph again and

[ftrandom] Various fixes.
* src/tools/ftrandom/ftrandom.c (GOOD_FONTS_DIR): Provide better
default.

this was completely broken.
Update all related code.
(error_count, fcnt): Make it unsigned to fix compiler warnings.
Update all related code.
(fontlist): Change `len' member to `long' to fix compiler warnings.
(FT_MoveTo, FT_LineTo, FT_ConicTo, FT_CubicTo, abort_test): Tag
unused variables.
(TestFace, FindFonts, copyfont, do_test): Fix compiler warnings.
(ExecuteTest): Ditto.
Call `FT_Done_FreeType'.

disable the stroke.

[smooth] Simplify span rendering more.
It turns out that there is significant cost associated with `FT_Span'
creation and calls to `gray_render_span' because it happerns so
frequently. This removes these steps from our internal use but leaves
it alone for `FT_RASTER_FLAG_DIRECT" to preserve API. The speed gain
is about 5%.
* src/smooth/ftgrays.c (gray_render_span): Removed. The code is
migrated to...
(gray_hline): ... here.

[smooth] Streamline pixmap drawing a bit more.
Zero coverage is unlikely (1 out of 256) to warrant checking. This
gives 0.5% speed improvement in dendering simple glyphs.

[smooth] Simplify span rendering.
This removes unnecessary complexity of span merging and buffering.
Instead, the spans are rendered as they come, speeding up the
rendering by about 5% percents as a result.

(gray_TWorker): Remove span buffer and related fields.
(gray_sweep, gray_hline): Updated.
* include/freetype/ftimage.h: Remove documentation note about
`FT_MAX_GRAY_SPANS', which was never in `ftoption.h' and is now gone.
