[sfnt, truetype] Register the tags for marginal fonts.
The first 32bit of standard TrueType variants is 0x00010000,
`OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac
OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
starting 0xA5 followed by `kbd' or `lst'. Considering the following
data could be parsed as conventional TrueType fonts, the header
checking is updated to allow these tags. It seems that recent Mac
OS X has already switched to normal TTF for these fonts.
See the discussion at
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0
* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
tags for Keyboard.dfont and LastResort.dfont.
* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
starts with TTAG_0xA5kbd or TTAG_0xA5lst.
* src/truetype/ttobjs.c (tt_face_init): Accept the face with the
format tag is TTAG_0xA5kbd or TTAG_0xA5lst.

[sfnt, truetype] Improve handling of missing sbits.
Requested by Behdad.
Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain
entries in the bitmap strike(s) for empty glyphs. Instead, they
rely that a space glyph gets created from the font's metrics data.
This commit makes FreeType behave accordingly.
* include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error
code.
* src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes
to make a distinction between a missing bitmap in a composite and a
simple missing bitmap.
* src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a
bitmap-only font), synthesize an empty bitmap glyph if metrics are
available.

contours if we have a composite glyph (this is for better backwards
compatibility I guess), but it still recommends value -1.

[sfnt, truetype] Always provide default instance.
As documented in the OpenType specification, an entry for the
default instance may be omitted in the named instance table. In
particular this means that even if there is no named instance table
in the font we actually do have a named instance, namely the default
instance.
For consistency, we always want the default instance in our list of
named instances. If it is missing, we try to synthesize it.
* src/sfnt/sfobjs.c (sfnt_init_face): Check whether the default
instance is in the table of named instances. Otherwise adjust
number of instances.
* src/truetype/ttgxvar.c: Include FT_TRUETYPE_IDS_H.

It's unavoidable to call the PNG engine, but to get the metrics it
is sufficient to read the PNG image's header only.

allocation of the glyph slot.

[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
argument to control allocation of the glyph slot.

[sfnt] Fix `FT_Get_Advance' for bitmap strikes.
`FT_Get_Advance' returns 0 for bitmap fonts. It first gets the
advance value from the font table and then scales it by the
`font->size->metrics->x_scale' field. But `FT_Select_Size' doesn't
set that value for bitmap fonts and the advance gets scaled to zero.
Taken from
