- Restored "dither" option for conversion from float -> byte images.

  This now is a post-process option only (used to be in render).
  It is only handled within the Imbuf/ module, on conversions from float
  to byte rect, which atm mostly happens on saving images.

- Small fix: when using Scene RenderLayer nodes, the speed vectors for
  these nodes were not created when that scene had "Do Composite" off.
