Hello,
Display window is not correctly support for all case in ffmpeg exr decoder.
Only datawindow < display window is supported, and if i correctly remember,
not for < 0 coordinates.
I begin to work on a patch for this, but i doesn't find time to finish it.
I will probably take a better look on this (but not soon), and it's
probably better to modify the decoder
to use planar format before implementing a full display/data window support.
