Render timeout too short for RasPi2 platform #1

Closed sonntam closed 4 years ago

See here.

The currently hard-coded render timeout of 10 seconds is too short. Maybe change the rendering so that no hard-coded timeout is necessary by observing the spawned process.

The default node's state machine can take as long as 40 seconds to render on a Pi2 according to this post.

As stated in https://github.com/sverweij/state-machine-cat/issues/116 using native graphviz would be a good way around the performance issue since rendering is done in the runtime - not in the client browser.

A couple of new features have been added:

Caching functionality that only need to redraw graphs if something changed or if they became too old (TTL of 4 weeks)
Ability to use graphviz's native dot renderer program. In order to use it it has to be available on the path.
