    lavu: Adding ARIB STD-B67 (hybrid log-gamma) enum value and transfer function. · 785038c9
    Neil Birkbeck authored Apr 21, 2016
    Adding hybrid log-gamma (https://en.wikipedia.org/wiki/Hybrid_Log-Gamma)
    based on the standardization in ARIB STD-B67:
    http://www.arib.or.jp/english/html/overview/doc/2-STD-B67v1_0.pdf
    
    The choice of enum value of 18 is consistent with HEVC:
    http://phenix.it-sudparis.eu/jct/doc_end_user/current_document.php?id=10481
    
    And also with latest proposal for color format in mkv:
    https://mailarchive.ietf.org/arch/search/?email_list=cellar&gbt=1&q=Colour+Format+proposal
    
    The implementation assumes a nominal input range of [0, 1], which is
    consistent with HEVC.
