Rendering of current status:#

• Should use some kind of mailbox processor
• When it gets triggered, it checks the current status and runs jj to fill the various buffers with the latest graph and such
• Should have a cache that gets invalidated whenever jj says there was a change

  • The cache can store the fully processed data for the view buffers iiee

    Status_state

  • We shouldn't use lwd.var to trigger this updating becasue that will intruduce at least one extra frame of delay:

key press   recompute vars and start rendering 
  |------------|---------------/
  render new state
/--|

As you can see there always needs to be at least one re-render just to start the rendering of the new command
