+
+ 2. range matches: of all faces in whose design range the

+ size is closest to is returned.
+
+ 3. out-of-range matches: of all other faces (i. e. whose range
+ is above or below the asked size) the one is chosen whose
+ boundary (upper or lower) is closest to the requested size.

+ 4. default matches: if no design size or a design size of zero

+ 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.
+
+ The first return value of “resolve_name” is the file name of the
+ requested font (string). It can be passed to the fullname resolver
+ get_font_file().

+ Fontwise kerning is enabled via the “kernfactor” option at font

+ Luatex attributes, it uses a font property for passing along the
+ letterspacing factor of a node.
+
+ The callback is activated the first time a letterspaced font is
+ requested and stays active until the end of the run. Since the font
+ is a property of individual glyphs, every glyph in the entire
+ document must be checked for the kern property. This is quite
+ inefficient compared to Context’s attribute based approach, but Xetex
