Base type for algebras that produce results in some effect type F. This type serves to make sure algebras are internally consistent. E.g. they all produce an effect with the same type.

Base module for constructors
Base module for constructors
The intention is to assist with type inference for constructors by defining constructors that are parameterized by the Algebra and Drawing types, and instantiating those types within each backend.
Algebras that define constructors should also define a constructor mixin. See e.g. Shape for an example.
Algebra describing color blending modes.
Algebra describing color blending modes.
Represents a picture, which is a function from a tagless final algebra to some type F that represents drawing a picture with result A. Has a monad instance if F does.

Higher level shape primitives. These draw common geometric shapes with the center of the shape the origin of the bounding box.

Algebra that represents converting from the Input type to a F[Unit] (that in turn can be wrapped in a Picture). This can be used to represent, for example, creating a picture from a bitmap in a base64 encoded string.
