1831e6f0689c8de6340774de1ad00fd3bb6ff924 15-Jul-2016 Werner Lemberg <wl@gnu.org> [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.

While this doesn't show up with FreeType, exactly the same code
leaks with ttfautohint's modified auto-hinter code (which gets used
in a slightly different way).

It certainly doesn't harm since it is similar to already existing
checks in the code for embedded arrays.

and `max_points' for all cases.

56ddafa01ce251d2f1f3adde3b0f72dd8ff7a405 14-Jan-2015 Behdad Esfahbod <behdad@behdad.org> [autofit] Add embedded array of segments and edges.

Avoids multiple mallocs per typical glyphs.

With this and recent changes to avoid mallocs, the thread-safe
stack-based loader is now as fast as the previous model that had one
cached singleton.

* src/autofit/afhints.h (AF_SEGMENTS_EMBEDDED, AF_EDGES_EMBEDDED):
New macros.
(AF_AxisHintsRec): Add two arrays for segments and edges.

* src/autofit/afhints.c (af_axis_hints_new_segment): Only allocate
data if number of segments exceeds given threshold value.

exceeds given threshold value.
(af_glyph_hints_done): Updated.

a632b5f4064873ab7f21b749f93332387bc47f76 03-Dec-2014 Werner Lemberg <wl@gnu.org> [autofit] Better fix for conversion specifiers in debug messages.

Using `%ld' for pointer differences causes warnings on 32bit
platforms. The correct type would be (the relatively new) `%td',
however, this is missing on some important platforms.

This patch improves the change from 2014-11-28.

* src/autofit/afhints.c (AF_INDEX_NUM): Use `int' typecast. Our
pointer differences are always sufficiently small.
(af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
af_glyph_hints_dump_edge): Revert to `%d' and use `AF_INDEX_NUM'.

8a94b1efd6cfe76ffbd66e9315542c9438a34722 12-Apr-2014 Werner Lemberg <wl@gnu.org> [autofit] Redesign the recognition algorithm of strong points.

In particular, local extrema without horizontal or vertical segments
are better recognized:

+ A + D
\ /
\ /
\ /
\ /
\ + C
\ /
B +/

If the distances AB and CD are large, point B wasn't previously
detected as an extremum since the `ft_corner_is_flat' function
`swallowed' BC regardless of its direction, tagging point B as weak.
The next iteration started at B and made `ft_corner_is_flat' swallow
point C, tagging it as weak also, et voilà.

To improve that, another pass gets now performed before calling
`ft_corner_is_flat' to improve the `topology' of an outline: A
sequence of non-horizontal or non-vertical vectors that point into
the same quadrant are handled as a single, large vector.

Additionally, distances of near points are now accumulated, which
makes the auto-hinter handle them as if they were prepended to the
next non-near vector.

This generally improves the auto-hinter's rendering results.

* src/autofit/afhints.c (af_glyph_hints_reload): Implement it.

* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
`AF_FLAG_NEAR'.

cc25e3ae12216380179506b9d5d9c25293966708 05-Aug-2013 Werner Lemberg <wl@gnu.org> [autofit] Improve handling of `near' points.

Points which are very near to each other are now marked as such.
The `weak' flag is then computed by using the `in' vector of the
first and the `out' vector of the last point of a group of near
points.

For example, this fixes the rendering of glyph `Oslash' in
`Roboto-Thin.ttf'.

* src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'.

* src/autofit/afhints.c (af_glyph_hints_reload): Introduce
the heuristic value `near_limit' to decide whether the current point
is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
Store good `in' vector (of last non-near point) in
`last_good_in_{x,y}' and use it as an argument to
`ft_corner_is_flat' if necessary.

This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.

To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

this is a major patch used to drastically improve the performance
of loading glyphs. This both speeds up loading the glypn vector
themselves and the auto-fitter.

note that we've started using inline assembler with GCC to
implement FT_MulFix, given that this function is so damn
important for the engine's performance.

the resulting speed-up is about 25%.

now seems to be 100% equivalent to the auto-hinter, while being
about 2% faster (which proves that script-specific algorithm
selection isn't a performance problem).
