[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.

[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.

[sfnt, truetype] Don't abort on invalid `maxComponentDepth'.
Since 2016-05-16 we detect infinite recursion directly.
* src/sfnt/ttload.c (tt_face_load_maxp): Don't adjust
`maxComponentDepth'.
* src/truetype/ttgload.c (load_truetype_glyph): Don't abort if
`maxComponentDepth' is not valid. Instead, simply adjust its value
and emit a tracing message.

[truetype] Record the end of IDEFs.
To match the logic in FDEF. The value of the end is only used for
bound-checking in `Ins_JMPR', so it may not have been obvious that
it was not recorded. Tested (as part of Font Validator 2.0) all the
fonts on Fedora and did not see any change.
* src/truetype/ttinterp.c (Ins_IDEF): Updated.

[truetype] Add support for Apple's
GETDATA[], opcode 0x92
bytecode instruction. It always returns 17, and we have absolutely
no idea what it is good for...
* src/truetype/ttinterp.c (Pop_Push_Count, opcode_name): Updated.
(Ins_GETDATA): New function.
(TT_RunIns): Add it.

[truetype] Add bytecode support for GX variation fonts.
This commit implements undocumented (but confirmed) stuff from
Apple's old bytecode engine.
GETVARIATION[], opcode 0x91
This opcode pushes normalized variation coordinates for all axes
onto the stack (in 2.14 format). Coordinate of first axis gets
pushed first.
GETINFO[], selector bit 3
If GX variation support is enabled, bit 10 of the result is set
to 1.
* src/truetype/ttinterp.c: Include FT_MULTIPLE_MASTERS_H.
(opcode_name) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Updated.
(Ins_GETINFO) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle selector
bit 3, checking support for variation glyph hinting.
(Ins_GETVARIATION) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: New function
to implement opcode 0x91.
(TT_RunIns) [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Handle opcode 0x91.

[truetype] More fixes for GX.
This finally fixes the rendering of the cyclist and the lizard in
the `Zycon' font.
* src/truetype/ttgxvar.c (ft_var_readpackedpoints): `first' point
index is always cumulative.
(tt_handle_deltas): Rename to...
(tt_interpolate_deltas): ... This.
Add new parameter for output point array.
Update caller.
(TT_Vary_Apply_Glyph_Deltas): Add `points_out' array; it now holds
the intermediate results of `tt_interpolate_deltas' that are to be
added to `outline->points'.

* src/autofit/aflatin.c (af_latin_hints_compute_segments): Thinko.
`max_pos' is always larger than `min_pos' so `FT_ABS' is not needed.

[autofit] Update and improve segment and edge tracing.
* src/autofit/afhints.c (af_glyph_hints_dump_segments): Trace
`delta' also.
Don't show first point of segment as a replacement for `pos'; this
is (a) misleading, since the difference to `pos' can be almost
arbitrarily large in corner cases, and (b) it is better to have all
segment data in font units instead of a single value given in output
space coordinates.
Improve layout.
(af_glyph_hints_dump_edges): Show px->units and units->px conversion
values for convenience.
Improve layout.

`delta'.

than 0.5px.

[truetype] Fix gxvar delta interpolation.
The coordinates of the base font should be used for interpolation
purposes, NOT the current points (i.e., the result of accumulation
of previous deltas).
* src/truetype/ttgxvar.c (TT_Vary_Apply_Glyph_Deltas): Initialize
`points_org' before looping over all tuples.
