Expand description

Composition for pipelines.

A pipeline can wrap another one and leave everything it does not change to it, which is how independent concerns — capping the frame rate, timing the passes, inspecting what a frame is about to draw — stack in any order.

A decorator forwards the passes it does not change to the pipeline it wraps; the default draw then runs those forwards as one frame. A pass it forgets to forward falls back to the standard implementation of that pass, not the inner pipeline’s, so a decorator must forward every pass it wants the inner pipeline to decide.
