Disable transition animation

[bigbug]

For large files the transition animation seems to lead to a higher computation time.
During experiments it was seen, that an initial rendering of the file took 15 seconds. Subsequent renders of the same file (with small changes on only one node) then took about 45 seconds. It was seen that removing

graphviz
  .fade(true)
  .transition(transition)
  .tweenPaths(true) // default
  .tweenShapes(true) // default

from the code lead to significant better render times.
The removal of this code could possibly reduce the render times. Maybe already lowering transition is sufficient. A mechanism could be implemented strip away the transition if the underlying DOT render of the previous DOT source took over 15?? seconds.

what about making this configurable or auto-sensing and disabling it if the input is larger than a threshold? 🤔
