[truetype] Apply MVAR hasc, hdsc and hlgp metrics to current FT_Face metrics.
Instead of setting typo or win metrics as the new FT_Face metrics
indiscriminately, apply only typo deltas to the currently active FT_Face
metrics. This prevents line height differences when e.g. the default
outlines were used as the regular face and instances for everything else.
* src/truetype/ttgxvar.c (tt_apply_mvar): Implement.

[truetype] Increase precision while applying VF deltas.
It turned out that we incorrectly round CVT and glyph point deltas
before accumulation, leading to severe positioning errors if there
are many delta values to sum up.
Problem reported by Akiem Helmling <akiem@underware.nl> and analyzed
by Behdad.
* src/truetype/ttgxvar.c (ft_var_readpackeddelta): Return deltas in
16.16 format.
(tt_face_var_cvt): Collect deltas in `cvt_deltas', which is a 16.16
format array, and add the accumulated values to the CVT at the end
of the function.
(TT_Vary_Apply_Glyph_Deltas): Store data in `points_org' and
`points_out' in 16.16 format.
Collect deltas in `point_deltas_x' and `point_deltas_y', which are
16.16 format arrays, and add the accumulated values to the glyph
coordinates at the end of the function.

[GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts

No change in functionality, of course.

[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.

[truetype] Make `IUP' gvar deltas do the same as Apple (#50832).
When points are not touched by gvar interpolation deltas, FreeType
gave a slightly different result than Apple's CoreText.
The OpenType working group will update the specification to document
the following behaviour: If the two points with deltas to the `left'
and `right' of the untouched point have the same coordinate, then
the inferred delta for the untouched point should be zero.

[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.
(TT_Get_MM_Var): Use `face->root.style_flags' as the number of named
instances.
Sythesize a named instance entry if necessary.
(tt_done_blend): Free `normalized_stylecoords'.
