00ae29fcd2 [pshinter] Tune PSH_STRONG_THRESHOLD_MAXIMUM value.
Before the change, the hinting engine frequently confused horizontal
stem and serif hints making some stems too thin and some serifs too
thick. The value was tuned using serif fonts from the URW+ base 35
collection.

* src/pshinter/pshalgo.c [PSH_STRONG_THRESHOLD_MAXIMUM]: s/30/12/.

338b4e8846 [type42] Fix FT_Get_PS_Font_Private for this format.
Since Type42 fonts don't have a 'Private' dictionary, the return value
should be `FT_Err_Invalid_Argument`.

* src/type42/t42drivr.c (t42_ps_get_font_private): Removed.
(t42_service_ps_info): Updated.

1680885aa5 [pshinter] Clear reused mask.
In PS hinter, memory allocations persist until the module is done.
Therefore, we have to clear reused masks.

ed0e2e76d8 [pshinter] Fix mask merging.
We forgot to update the number of bits when merging a larger mask
into a smaller one.  This fix might have rendering effects.

* src/pshinter/pshrec.c (ps_mask_table_merge): Inherit the number
of bits from a larger mask. There is no need to zero unused bits,
already zeroed during allocation.
(ps_mask_clear_bit): Removed.
(ps_mask_ensure): Minor.

check; avoid array zeroing because it is fully initialized when used.
(ps_hint_table_alloc): Fix off-by-one comparison and remove another
zeroing of the array elements.

8e39e42ee9 [psaux] Revise PS_Table handling.
The old impleemntation was not using `FT_REALLOC`, buing too careful
with the offset rebasing.  It shoudl be safe to rely on the base
movements.

* src/psaux/psobjs.c (reallocate_t1_table, shift_elements): Combine
into...
(ps_table_realloc): ... this function based on `FT_REALLOC`.
(ps_table_done): Simplified.

e34a860a07 Document FT_Outline_Decompose degenerate segments.
`FT_Outline_Decompose` does not filter out and can return degenerate
segments in an outline. This can be surprising when attemping to
stroke such an outline. Clarify the existing documentation on this
matter to cover all forms of degeneracy (without specifying exactly
how they will be reported), why they might arise, and better explain in
what cases they may be an issue.

* include/freetype/ftoutlin.h (FT_Outline_Decompose): update
documentation.

Fixes #952.
