[aat] Allow disable feature ranges
...
Fixes https://github.com/harfbuzz/harfbuzz/issues/4020
This is a hack.
To implement this properly we need to treat runs with different features
as independent runs for running the state machine, as the subtable flags
might be different. That would be a significant change to our internal
implementation.

Narrow down cast operators on IntType
...
Say for USHORT, we were implementing casts from and to unsigned.
With this change, we cast from and to uint16_t only. This allows
compiler more opportunities to catch possible narrowing issues in
the code.
It needed a couple of fixes in the codebase though, because
previously, if a USHORT was participating in arithmetic with signed
numbers, eg. "u + 1", the result would have been unsigned. With
this change, it would be signed. The correct fix is to update the
code to read "u + 1u".
That said, I think about conditionally adding back the cast
out to signed/unsigned, to facilitate better type deduction.
But I couldn't think of a real situation where that would help
with anything. So I didn't add. Here's what it was:
template <typename Type2 = hb_conditional<hb_is_signed (Type), signed, unsigned>,
hb_enable_if (sizeof (Type) < sizeof (Type2))>
operator hb_type_identity_t<Type2> () const { return v; }

Glyph insertion is an expensive operation and we like to have it limited
based on buffer's input size which is handled by buffer's max_ops.
