* src/truetype/ttgload.c (TT_Hint_Glyph): Remove useless test.
`control_len' only gets its value from `n_ins' (and vice versa),
which is always read as `unsigned short' and thus can't be larger
than 0xFFFF.

Fix handing of `FT_Bool'.
Before this commit we had code like
(FT_Bool)( globals->glyph_styles[gindex] & 0x8000)
Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like
(unsigned char)( 0x8532 & 0x8000)
which in turn expanded to
(unsigned char)( 0x8000)
and finally yielded 0x00 – i.e., false – not as expected.
Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>.
* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.
*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.

[truetype] Avoid nested frames.
Triggered by

* src/truetype/ttgload.c (load_truetype_glyph): Don't use variable
`opened_frame' to trace whether a frame must be closed at the end of
function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which
gets called for space glyphs) uses a frame by itself. Instead,
close the frame after loading the header, then use another frame for
the remaining part of the glyph later on.

[sfnt] Preliminary support of coloured layer outlines.
This commit enables OpenType's COLR/CPAL table handling; a typical
application are color emojis that can be scaled to any size.
If the color palette does not exist or is invalid, the rendering
step rasterizes the outline instead. The current implementation
assumes that the foreground is black.
Enable this by defining option TT_CONFIG_OPTION_COLOR_LAYERS.
There are still some issues with metrics; additionally, an API to
fetch color layers is missing.

[cff, truetype] Adjust behaviour of named instances.
This commit completely separates the interaction between named
instances and variation functions. In particular, resetting the
variation returns to the current named instance (if set) and not to
the base font.
As a side effect, variation functions no longer change the named
instance index.
* src/cff/cffobjs.c (cff_face_init): Use MM service's `set_instance'
function.
Also apply `MVAR' table to named instances.
* src/truetype/ttgxvar.c (TT_Get_MM_Var): Add cast.
(tt_set_mm_blend): No longer check whether requested variation
coincides with a named instance.
(TT_Set_Var_Design): Use current named instance for default
coordinates.
* src/truetype/ttobjs.c (tt_face_init): Use `TT_Set_Named_Instance'.

[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.
