Matthias Clasen f81578fd86 [ot-layout] Synthesize missing baselines 
Add a variation of hb_ot_layout_get_baseline that

taken from the CSS Inline Layout Module, Level 3.

Includes some new tests for synthesized baselines.
The base2.ttf is a subset of Noto Sans Bengali that
includes just the Bengali Ka.

Khaled Hosny 69d8f27c69 [meson] Require 0.55.0 
We implicitly require it for building ragel subproject. This new version
requirement should satisfied in both Fedora 33 and Debian bullseye, and
not be too cutting edge for us.

Behdad Esfahbod da500568de [API] Add hb_buffer_[sg]et_not_found_glyph() and --not-found-glyph 
Instead of using gid=0 when a character is not found in the font,
client can now set a custom value.  This is useful for shaper-driven
font fallback and to differentiate that from .notdef glyph.

Date:   Thu Jun 18 10:55:13 2015 -0700

    [util] Disable hb-fc-list for now
