    Fix T50243: libmv_panography_test is broken
    
    There was fully wrong logic in comparison: was actually accessing memory
    past the array boundary. Run test manually and the figure seems correct
    to me now.

    Add basic track masking API in place
    
    This brings back ability to mask non-interesting parts of
    specific track (the feature got lost with new auto-track API).
    
    Added it back by extending frame accessor class. This isn't really
    a frame thing, but we don't have other type of accessor here.
    
    Surely, we can use old-style API here and pass mask via region
    tracker options for this particular case, but then it becomes much
    less obvious how real auto-tracker will access this mask with old
    style API.
    
    So seems we do need an accessor for such data, just matter of
    finding better place than frame accessor.

    - Update Eigen to 3.2.7 since this brings crucial
      fixes for MSVC 2015.
    
    - Switch to STATIC build by default.
    
      There are issues building current sources as dynamic
      libraries with MSVC2015 and additionally building
      dynamic Ceres is not recommended anyway, so let's
      not do this for the time being.
    
    If anyone finds a way to make this all working --
    it'llsurely be a welcome addition.

      differently from Blender side.

    Main purpose of this (andsome of upcoming) update is to check if the

    not, then we'll need to consider moving some changes into upstream.
    
    This commit contains an one-to-one copy of the upstream GFlags library

    Libmv: Support disabled color channels in tracking settings
    
    This was never ported to a new tracking pipeline and now it's done using
    FrameAccessor::Transform routines. Quite striaghtforward, but i've changed
    order of grayscale conversion in blender side with call of transform callback.
    
    This way it's much easier to perform rescaling in libmv side.

    implement backward prediction
    
    The title actually says it all, just extend current implementation
    of PredictMarkerPosition() to cases when tracking happens in the reverse
    order (from the end frame to start).
    
    it's still doesn't solve all the ambiguity happening in the function
    in cases when one tracks the feature and then re-tracks it in order
    to refine the sliding. This is considered a separate TODO for now and
    will likely be solved by passing tracking direction to the prediction
    function.

    Fix search area sliding issue
    
    The only way to do this is to store search region in floats
    and round when we need to sample it. Otherwise you'll always
    have sliding effect caused by rounding the issues, especially
    when doing incremental offset (thing which happens in the
    prediction code).
    
    Pretty much straightforward change apart from stuff to be kept
    in mind: offset calculation int should happen relative to the
    rounded search region. This is because tracker works in the space
    of the search window image which get's rounded on the frame access,
    
    This makes API a bit creepy because frame accessor uses the same
    Region struct as the search window in Marker and ideally we would
    need to have either IntRegion or Region<int> in order to make
    Libmv fully track on what's getting rounded and when.
