"""Render a workflow graph.
This macro accepts a TracWorkflow configuration and renders the states
and transitions as a directed graph. If no parameters are given, the
current ticket workflow is rendered. In WikiProcessors mode the `width`
and `height` arguments can be specified.

Examples:
{{{
[[Workflow()]]
[[Workflow(go = here -> there; return = there -> here)]]
