This namespace lists utility functions attached to an instance of Rac during initialization. Each drawable and style class gets a corresponding function like rac.Point or rac.Color.

Drawable and style objects require for construction a reference to a Rac instance in order to perform drawing operations. The attached functions build new objects using the owning Rac instance.

These functions are also setup with ready-made convenience objects for many usual values like rac.Angle.north or rac.Point.zero.
