Behdad Esfahbod 1d9dafbfd5 [glyf] Support cubic curves 
https://github.com/harfbuzz/boring-expansion-spec/issues/41

Behdad Esfahbod 64fa5cd482 [GPOS] Fix assert fail introduced recently 
Was introduced in 8708b9e081.

If these lookups are recursed to from (Chain)Context out-of-order,
it was possible that last_base > buffer->idx, in which case we
were attaching marks to a base after them... and an assertion
was failing fortunately.
