pub const DENSITY_CHOICES: [(Option<Density>, &str); 3];Expand description
What a FieldKind::Density picker offers, in order, and what each entry
is called.
None is “follow detection”, which is also what an empty store means.
Here rather than in each host because the words are the description’s:
a webview’s select and an egui combo box offering the same three things
under different names would be two pickers. “Mouse and trackpad” rather
than “Pointer” because the reader is choosing by what is in their hand,
not by the preset’s name.
