This patch adds units to the Cycles properties as requested in T60824.
I've fixed some inconsistent quotation marks in the file as well.
Looks good to me
This is a factor relative to the image size, not in pixels.
This is a length, not in pixels.
You're right, I was following the remarks of T60824 without checking if the subtype and unit actually matches.
So removing the subtype from camera_cull_margin and make distance_cull_margin a length?
The camera cull margin is now of subtype FACTOR and the cull distance of unit LENGTH.
Marked @Brecht Van Lommel (brecht) comments as done.
