FEATURES =

Standard features available in this display service - see KNOWN_FEATURES. These may or may not require the Shoes.app requesting them per-app.

[]
EXTENSIONS =

Nonstandard extensions, e.g. Scarpe extensions, supported by this display lib. An application may have to request the extensions for them to be available so that a casual reader can see Shoes.app(features: :scarpe) and realize why there are nonstandard styles or drawables.

[]
KNOWN_FEATURES =

These are all known features supported by this version of Lacci. Features on this list are allowed to be in FEATURES. Anything else goes in EXTENSIONS and is nonstandard.

[
  :html, # Supports .to_html on display objects, HTML classes on drawables, etc.
