Add size_reset to MetricsVariations
This is a generalization of "[truetype] Fix MVAR post-action handling."
[0]. It is also possible for plain CFF
style fonts to contain an
fvar
and MVAR
table and use cff_metrics_adjust
. tt_size_reset
should only be called with TT_Size
and never with CFF_Size
.
Allow the "metrics-variations" service to specify the correct function
(if any) to reset FT_Size
s after adjusting metrics.
