/* LIMITATIONS
    From MeBase:
      Only frame mode, only Y is used.
    From MPEG
      Only 16x16, only half-pixel.
    Only frame size, search range and BlockVarThresh parameters are used in this ME.
  Changes in MeBase:
    Added to MeParams BlockVarThresh field, which is quantizer value of mpeg.
    Added to ME_MB skipped field, which signals that current MB with provided MV can be skipped.
  Difference in returned results:
    returned MV are half-pixel precision.
    FW vector always returned in [0] and BW always in [1], even when no FW vector.
    When is skipped, all required vectors are set and cost returned in [0].
    For bidir prediction 3 costs are returned - [0]-FW, [1]-BW, [2]-bidir.
