    This changes the ext_linear default primary color volume minimum back to
    0.2 cd/m². This is consistent with the sRGB reference display
    characteristics, like with all other transfer functions except st2084_pq
    and hlg.
    
    The purpose is that whether content uses srgb, gamma22 or ext_linear
    transfer function, it occupies the same (sRGB SDR) dynamic range by
    default.
    
    For rendering intents that employ black-point compensation, including
    the perceptual rendering intent, this changes nothing.
    
    The set_luminances request can be used to set more appropriate values as
    necessary.

    Removed the wording about implied luminances, because it applies to
    almost all TFs, not just this one.
