Ebrahim Byagowi 63109432cf Cosmetic and minor changes 2018-10-13 07:23:33 -04:00
Behdad Esfahbod 477bc9aafe Add hb-ot-name.h 
Actual name-fetching API to come later.

New API:
hb_name_id_t
HB_NAME_ID_INVALID
 2018-10-12 16:06:39 -04:00
Ebrahim Byagowi dc49bd8d81 Add two APIs for getting stylistic set labels 
* hb_ot_layout_feature_get_characters
* hb_ot_layout_feature_get_name_ids

However HarfBuzz currently doesn't expose an API for retrieving the actual
information associated with NameId from the `name` table and that should be
done separately.

Behdad Esfahbod 606bf57430 Revert forcing use of single-parameter static_assert() 
Some clang versions define static_assert as a macro apparently, so we cannot
redefine it...

This reverts commit 94bfea0ce6.
This reverts commit 4e62627831.
 2018-09-16 19:34:39 +02:00
Behdad Esfahbod 4e62627831 Enforce single-param static_assert() only 
So we don't accidentally break it again.

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 9507b05a7a Simplify sanitize->check_array() 
Fix a bug in CBDT sanitize, and redundant check in avar.

Behdad Esfahbod fda994e1d4 Use enum instead of "static const" in class scope 
Technically, static const needs an out-of-class definition.  Eg:
