(Added a minor fix, checking for retinex->scales being NULL too for deciding if
it needs to be reallocated)

    opencv: Add colour image enhancement element based on Retinex algorithm

    Add colour image enhancement element based on Retinex algorithm. Two types
    exist, namely basic and multiscale; both are described in this article:

    Rahman, Zia-ur, Daniel J. Jobson, and Glenn A. Woodell. "Multi-scale
retinex
    for color image enhancement." Image Processing, 1996. Proceedings.,
    International Conference on. Vol. 3. IEEE, 1996

    Visually speaking the result looks a bit funny, but is pretty invariable to
    lightning changes, which is good for some applications, like image
    segmentation.
