These public API functions(!) were always undocumented and have
escaped all clean-up efforts until now.
* include/freetype/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Removed.
* src/base/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Merge into...
(FT_Outline_New, FT_Outline_Done): ... these functions.
* docs/README: Updated.
* include/freetype/fterrors.h (FT_INCLUDE_ERR_PROTOS,
FT_ERR_PROTOS_DEFINED): Undefine `FT_INCLUDE_ERR_PROTOS' after
checking it and introduce a new macro that takes proper care of
multiple-inclusion protection.
* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
Change return type.
* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Return the bitmap
size assessment.
* src/raster/ftrend1.c (ft_raster1_render): Use it to refuse the
rendering of enourmous or far-fetched outlines.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto.
* src/autofit/afhints.h (AF_PointRec) [FT_DEBUG_AUTOFIT]: New arrays
`before' and `after'.
* src/autofit/afhints.c (af_get_strong_edge_index): New auxiliary
function.
(af_glyph_hints_dump_points): Trace `before' and `after' edges.
(af_glyph_hints_align_strong_points) [FT_DEBUG_AUTOFIT]: Set
`before' and `after' information.

* src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_roll>
[CFF_CONFIG_OPTION_OLD_ENGINE]: Use modulo for loop count, as
documented in the specification.

https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054
* 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.
Also avoid calling `tt_get_metrics' twice under some circumstances.
Add checks, rules and variables to the build system for docwriter.
* Running `make' will warn if Python/PIP/docwriter are not available.
* Running `make refdoc' will generate static documentation site on the
current Python environment.
* Running `make refdoc-venv' will generate static documentation site
using a virtual environment, using the pip package `virtualenv'.
Add the required resources (images, JS, CSS) for `docwriter'.
* docs/reference/.gitignore: Update to ignore `site' folder and other
files generated by docwriter.
* docs/reference/README: Add docwriter usage information and
troubleshooting tips.
* docs/reference/markdown: New directory to hold generated markdown
files and other resources.
* include/freetype/internal/ftcalc.h (ADD_INT64, SUB_INT64,
MUL_INT64, DIV_INT64) [FT_LONG64]: New macros.
* src/base/ftcalc.c (ft_corner_orientation) [FT_LONG64]: Use
`SUB_INT64' and `MUL_INT64'.

* src/truetype/ttgload.c (ON_CURVE_POINT, X_SHORT_VECTOR,
Y_SHORT_VECTOR, REPEAT_FLAG, X_POSITIVE, SAME_X, Y_POSITIVE, SAME_Y,
OVERLAP_SIMPLE): New macros.
(TT_Load_Simple_Glyph): Use new macros to make code more readable.
Remove useless adjustment of `outline->tags' elements.
