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 :)
