ca97ea7aa2 [ft] Revert change-of-behavior of hb_ft_font_create() introduced in 1.0.5 
The default FreeType load flags where changed from FT_LOAD_NO_HINTING
to FT_LOAD_DEFAULT in 2a9627c564.
This is crashing HarfBuzz-enabled FreeType as I suppose it causes
infinite recursion between HB and FT autohinter...

Revert the behavior change.

613e630617 Reduce max nesting level from 8 to 6 
We probably should implement better system to catch cyclic lookups.
But for now, this speeds up worst case behavior with broken fonts
considerably without compromising legitimate usecases.

parent into a font...

2a9627c564 [ft] API: Add hb_font_[sg]et_load_flags() API 
This changes the default load_flags of fonts created using
hb_ft_font_create() from NO_HINTING to DEFAULT.  Hope that doesn't
break too much client code.

Code calling hb_ft_font_set_funcs() is unaffected.

1866e17114 Make hb_font_create_sub_font() NOT make parent immutable 
We don't rely on that.  However, whenever hb_font_make_immutable()
is called, it makes its parenting chain immutable.

f2ad935e19 Handle language tags that indicate phonetic IPA transcription 
The BCP-47 registry defines a variant subtag "fonipa" that can be used
in combination with arbitrary other language tags. For example,
"rm-CH-fonipa-sursilv" indicates the Sursilvan dialect of Romansh
as used in Switzerland, transcribed used the International Phonetic
Alphabet.

5d74ff02ab Fix Since: version tags on font and face APIs 
A while back we marked every API as version:1.0.  We should fix them all
to reflect real version they were introduced.  This is a start.
