== Sequencer ==

* documented and rewrote the render interface of the sequencer.
  (now, the geometry / render_type / etc. settings are stored within a
  seperate structure called SeqRenderData that is passed within the code.)

* that fixes
  * cache problems, since the caching system didn't keep track of
    proxy files vs. final renders.
  * is a necessary step, to bring back frame blending in speed effect
    (the SeqRenderData structure elements are already there)
  * will make motion blur render options available within the sequencer!

* this patch also fixes:
  * "easy retiming" using speed effects. (in Blender 2.49, you could 
    add a speed effect and resize the source track to retime it to that
    length)
  * adds labels for the Original dimensions for Image + Movie tracks
    (worked in 2.49, too)
