Description:
Once we set support for OpenType Font Variation, we need to implement a
converter to convert its instances into static glyphs before variable font used
for printing and experting to PDF. According to OpenType Font Variations
Overview:[1]

“In certain application workflows, it may be necessary to dynamically generate
a static font resource for a particular instance — that is, conventional,
non-variation font tables that use interpolated values for a particular
instance. This may be needed in order to provide font data to legacy software
or data formats that do not understand or support variable fonts, such as
legacy printer drivers, or PDF or XPS files with embedded font data. ”
