Ton Roosendaal f7c9c99877 Bugfixes from own collection: 
- when renderwin exists, but not used for render, the ESC timer check still
  could return ESC event, due to missing flag clearing.
  (For example in sequencer, a scene strip did not update on frame advance)

- option 'single layer' set in combination with render "Do Sequence" didn't
  free the pushed layers.

1) Initialize state

- camera, world, matrices
- make render verts, faces, halos, strands

3) Render Processor
- multiple layers
