New:

- ZTransp render now also delivers Z values and Speed vectors in passes
  Note that speed vectors accumulate within a pixel to store the minimum,
  so rendering ztransp on top of a non-moving plane won't give speed...
  Best results you get is by rendering it in a separate layer.

  The Z value stored is the closest visible transparent face in the pixel.

Fixes:

- Render to 'spare page' has been enabled again. Because of the strict
  separation of Render and UI, but especially because a 'render result' now
  can consist of unlimited images, I've not made this a Render feature.
  Instead, the render-window itself stores the 'spare' image... I also
  had to change the convention for it a bit.

  Now, instead of having two "render buffers" (which was a render feature),
  the RenderWindow will store each previous frame on a re-render. This
  storing will only start after you've pressed 'Jkey' once, but then always
  will happen for as long the rendered image is same size as previously.
  For clarity, I've also renamed the window title, to 'previous frame'.

- RenderWindow shows alpha again on Akey

- Display of the Zvalues in ImageWindow has been tweaked. White now denotes
  closest, and the color range goes from camera clip-sta to clip-end.

- Bugfix: on splitting/merging/duplicating windows, the 3D Previewrender was
  not always freed correctly, potentially causing crashes or memory leaks.
