---    --- tl;dr: font style synonyms are unreliable.
---    ---
---    --- Context matches font names against lists of known identifiers
---    --- for weight, style, width, and variant, so that including
---    --- the family name there are five dimensions for choosing a
---    --- match. The sad thing is, while this is a decent heuristic it
---    --- makes no sense to imitate it in luaotfload because the user
---    --- interface must fit into the much more limited Xetex scheme that
---    --- distinguishes between merely four style categories (variants):
---    --- “regular”, “italic”, “bold”, and “bolditalic”. As a result,
---    --- some of the styles are lumped together although they can differ
---    --- significantly (like “medium” and “bold”).
---
---    --- Xetex (XeTeXFontMgr.cpp) appears to recognize only “plain”,
---    --- “normal”, and “roman” as synonyms for “regular”.

---        regular    = { "normal",         "roman",
