@brief OpenType typographic feature
@m_since_latest
The values are [FourCC](https://en.wikipedia.org/wiki/FourCC) codes according
to the [OpenType feature registry](https://learn.microsoft.com/typography/opentype/spec/featurelist).
See also the [List of typographic features](https://en.wikipedia.org/wiki/List_of_typographic_features#OpenType_typographic_features)
on Wikipedia for the values grouped by use case. Use
@ref feature(char, char, char, char) or @ref feature(Containers::StringView)
for creating values not listed in the enum.
Currently, there's no corresponding feature list for [Apple Advanced Typography](https://en.wikipedia.org/wiki/Apple_Advanced_Typography).
Mapping from OpenType features to AAT features is possible but nontrivial, and
is the responsibility of a particular font plugin.
