    m42634/raht: added rahtLeafDecimationDepth control · 34da2afb

    This commit introduces the rahtLeafDecimationDepth parameter to allow
    chroma sub-sampling by decimating the coefficients in the bottom n
    levels of the tree.
    The default value of 3 provides chroma sub-sampling by a factor of 2
    in each dimension.
