Detailed Description

NDC-to-value mappings, inverse to the forward placement performed by geometry functions.

Each function returns a callable suitable for direct use as the projection argument of Portal::Forma::Geometry::wire_drag. They are pure: no window, no context, no element. A projection paired with the geometry function that shares its parameters is what makes a control draggable.
