This change restores the behavior of the flag to how it was prior to
the refactor which used ImBuf for storage in the RenderResult.
This flag still has issues with configurations when there are multiple
scenes in the .blend file, and that it is only "valid" when the image
is actually displayed. However, these limitations and quirks already
existed prior to the refactor commit.
