Combining diagrams

(<|>) :: Diagram -> Diagram -> Diagram infixl 2 Source

overlay; the second diagram is over the first one

union :: [Diagram] -> Diagram Source

overlay generalized to several diagrams

pack :: Diagram -> (Diagram -> Diagram) -> Diagram Source

pack a diagram; (pack d f) is the more efficient version of (let v=d in f v).
