ttf_glyph_outline() decodes simple-glyph flag/coordinate runs and
recursively resolves composite components into a caller-supplied point/
contour-end buffer, in Q48.16. Composite scale/rotation/skew transforms
are rejected with TTF_ERR_UNSUPPORTED rather than mis-rendered, since the
shared q48_mul/q48_div are unsigned-only; translation-only composites
(the only kind the v1 glyph repertoire uses) apply cleanly via q48_add.

Freestanding C module resolving a Unicode codepoint (cmap format 4) to a
glyph index and its outline header (contour count, bounding box), verified
against an independent from-scratch Python reference reader via
tools/ttftest.c. Not yet wired into the boot path or capsule system.
