More work on 3d view render:

- reverted fix for bug 32537 (error report drawing after thread job didn't show)

  This solves very bad 3d view render updates while using transform, it was
  getting into an eternal feedback loop for dependencies. (jobs sending mousemoves
  causing jobs to end, causing mousemoves, causing etc).
  
- The render-update code was not going over all windows, but over every screen to
  send signals (also the invisble ones)
