Behdad Esfahbod 3bf91bd269 [color] Rewrite colr access
COLR table has one function: return layers for a glyph, and we expose exactly
that, so should just wire it through.  Also use sub_array() for verifiable
safety.

Also, BaseGlyphRecord's null object is enough.  We don't need to special-case
the not-found.

Behdad Esfahbod a6ade3471e [colr] Move sanitize() to right place
Sanitize always comes just before data member definitions, so
it's easy to cross-check.

Behdad Esfahbod 24adc15757 [colr] Touch up a bit
When a struct is plain old data with no references, etc, it's okay

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.
