It's a cumulative process.
(1) Start with an empty outline.
(2) Take subglyph 0 (with n0 points having indices 0, 1, 2, ..., n0-1)
and add it according to the subglyph flags (for example, the glyph
might transformed and translated).
(3) Add subglyph 1 (with n1 points having indices 0, 1, 2, ..., n1-1)
and add it according to the subglyph flags. The merger of
subglyphs 0 and 1 has n0 + n1 points, with indices 0, 1, 2, ...,
n0+n1-1)
Repeat (3) until you are done.
