I would like to use swscale to convert a float/half image into a ProRes 
yuv420p10 (or some other yuv format) with my code.  Currently the exr 
support in ffmpeg is minimal and is limited to exr.c (it does not 
support all compression formats, it does not support multichannel nor 
multipart images, etc ).
