When you wanted to display "Chroma VectorScope" or "Luma WaveForm" for
image/window with small width/height, then Blender crashed, because
Blender has used fixed limits of ibuf->rect size. Statistics informations
should be created corectly now too.
- blur works again (this was a serious bug in gamwarp...)
- seperates all sequence effects into a seperate file with a clean interface
- thereby fixing some obscure segfaults
- seperates the scope views into a seperate file
- adds float support to all effects and scope views
- removes a bad level call to open_plugin_seq
- FFMPEG seeking improved a lot.
- FFMPEG compiles with debian sarge version cleanly
- Makes hdaudio seek and resample code really work
