-Luatex-fonts, the font-loader package luaotfload imports, comes with
-basic file location facilities (see luatex-fonts-syn.lua).
-However, not only does the builtin functionality rely on Context’s font
-name database, it is also too limited to be of more than basic use.
-For this reason, luaotfload supplies its own resolvers that accesses
-the font database created by the luaotfload-tool script.
+ choose_size -- Pick a font face of appropriate size from the list
+ of family members with matching style. There are three categories:
---doc]]--
+ 1. exact matches: if there is a face whose design size equals
+ the asked size, it is returned immediately and no further
+ candidates are inspected.
+ 2. range matches: of all faces in whose design range the
+ requested size falls the one whose center the requested
+ size is closest to is returned.
----
---- the request specification has the fields:
----
---- · features: table
---- · normal: set of { ccmp clig itlc kern liga locl mark mkmk rlig }
---- · ???
---- · forced: string
---- · lookup: "name"
---- · method: string
---- · name: string
---- · resolved: string
---- · size: int
---- · specification: string (== <lookup> ":" <name>)
---- · sub: string
----
---- The “size” field deserves special attention: if its value is
---- negative, then it actually specifies a scalefactor of the
---- design size of the requested font. This happens e.g. if a font is
---- requested without an explicit “at size”. If the font is part of a
---- larger collection with different design sizes, this complicates
---- matters a bit: Normally, the resolver prefers fonts that have a
---- design size as close as possible to the requested size. If no
---- size specified, then the design size is implied. But which design
---- size should that be? Xetex appears to pick the “normal” (unmarked)
---- size: with Adobe fonts this would be the one that is neither
---- “caption” nor “subhead” nor “display” &c ... For fonts by Adobe this
---- seems to be the one that does not receive a “prefmodifiers” field.
---- (IOW Adobe uses the “prefmodifiers” field to encode the design size
---- in more or less human readable format.) However, this is not true
---- of LM and EB Garamond. As this matters only where there are
---- multiple design sizes to a given font/style combination, we put a
---- workaround in place that chooses that unmarked version.
