Controls how a plugin fetched fielded imagery from a clip.
This controls how a plug-in wishes to fetch images from a fielded clip, so it can tune it behaviour when it renders fielded footage.
Note that if it fetches kOfxImageFieldSingle and the host stores images natively as both fields interlaced, it can return a single image by doubling rowbytes and tweaking the starting address of the image data. This saves on a buffer copy.
