Behdad Esfahbod ad28f973f3 Rename offset types to be explicit about their size 
Add Offset16To<>, Offset24To<>, and Offset32To<> for most use-cases.

[cpal] revert port to dagger 
It has a different semantic, maybe we should just do a zero memset,
letting Behdad to decide.

Behdad Esfahbod fedd8e6c17 One more......... 
I wonder if there's something better to do about these :(.

In file included from hb-ot-color.cc:31:
hb-ot-color-cpal-table.hh: In member function 'unsigned int OT::CPAL::get_size() const':
hb-ot-color-cpal-table.hh:118: error: ISO C++ says that these are ambiguous, even though the worst conversion for the first is better than the worst conversion for the second:

Behdad Esfahbod 6ce49a921a [name] Change hb_name_id_t back to unsigned int

 2018-10-28 08:26:30 -07:00
Behdad Esfahbod d941f66c75 [name] Make hb_name_id_t be the enum 
This is like hb_script_t.

We had this exposed as unsigned int since 2.0.0 release in two APIs,
as well as hb_ot_layout_get_size_params() from earlier.
But since no one uses those (right?!), let's just fix this now.

Behdad Esfahbod f3336580dd [color] Use hb_array_t in CPAL 
Doesn't work though, ouch :(.  Need to figure out if it's unreasonable
to expect Null(T) inside hb_array_t<T> to see the later specialization
of Null for NameID.

Khaled Hosny d4e928b142 [color] Minimal API for COLR/CPAL 2018-10-22 10:17:31 +02:00
Behdad Esfahbod 10642b3fbf Disallow null-enabled offsets to unsized structures... 
...like UnsizedArrayOf<>.

This fixes a class of crasher bugs, mostly with color and AAT tables.  We
cannot use nullable offsets to varsized data that does not declare min_size,
because it's nost safe to use our fixed-size null pool for types that have
their size external.  So, use non_null'able offsets for these.

A further enhancement would be to make use of min_size in Null<> itself.
Will try that after.

Behdad Esfahbod c77ae40852 Rename hb-*private.hh to hb-*.hh
