}TableProvider
Table provider abstraction.
Upstream skrifa is built on top of read-fonts which exposes a TableProvider
trait returning raw table bytes by tag. In MoonBit we keep FontRef::table
as the low-level primitive (UInt tag), and provide this trait adapter for
Tag-based APIs.

- base metrics from hmtx
- variation deltas from HVAR
- glyph-variation phantom-point deltas from gvar

This is intended for internal routines that apply the FreeType-style
mul_div(value, scale, 64) pattern.
Size::linear_scale
