The pictures a drawn enum is chosen by (spec/14 §18.6).
Some enums name a look — the join of a stroke, the shape of a curve, a symbol, a side —
and a person chooses a look by seeing it. glyph/2 draws one allowed value of a drawn
key as a small inline SVG, in currentColor so it reads in either theme; drawn?/1
says which keys have pictures. A curve is drawn by Visualize.Shape.Line and a symbol
by Visualize.Shape.Symbol, so the picture is the library's own work and cannot lie.
This module compiles only when Phoenix.Component is loaded (spec/10 §1.1, D-45, D-85).
Summary
Functions
Whether a key's enum is chosen by its picture.
The inline SVG for one value of a drawn key, or nil for a key that is not drawn or a
value it does not know.
The inline SVG of a control's icon — :eye and :eye_off for the layer toggle, :lock
for a library layer and :lock_open for one unlocked from it (spec/14 §18.8), :inspect, :colour and :variables for the
panel row, and a root's name (a string) for the node row (§18.13, #314) — in
currentColor, 18px, hidden from readers since the control names itself.
