cylc graph - search for task?

[ColemanTom]

I was thinking it might be useful to be able to, in graph view, do a search for a specific task. In particular, I've done a cylc graph suite.rc.processed on a particular system, curious to see the triggering around a specific task (I find this suites graph section a bit large to follow from casual inspection). But then, I had to find the task in the cylc graph display. It would be handy to have a navigate to task matching some glob or regex pattern, and you can cycle through the matches.

Is this at all feasible?

I'm not talking about a running suite, as typically they wouldn't display every single task all at once, so are a bit more manageable.

This is sort of related to cylc/cylc-flow#2566.

Yeah, this would be useful, and is feasible (but I think we have higher priorities for a while).

This could be extended to a static version of cylc/cylc-flow#2566: we should able to generate a graph of just the dependencies around a given task (to a configurable depth).
