== RED one (redcode) ==

This adds redcode (the file format of RED one, R3D) support to blender.
Seems to work fine with the footage I found on the web, but keep in
mind, that because of the unoptimized nature of libopenjpeg, frame
decoding isn't that fast.

It is also a rather challenging task, to make 4k-float-footage realtime :)
