// Decide what the base warp model should be when using WARP_DELTA.

//
// The MV which should be used at the center of this block is stored in
// `center_mv`. Once the non-translational parameters have been set,
// the translational part of the model can be set correctly using:
// av1_set_warp_translation(mi_row, mi_col, bsize, mv, params);
//
// If `center_mv` is not needed, the pointer can be set to NULL.
//
// The logic behind doing this is as follows:
// * If the current block is GLOBALMV, then we want to use the motion vector
// inferred from the global model. Conveniently, in this case that is already
// stored in mbmi->mv[0]
//
// * If the current block is NEWMV, then we want to use the signaled
// motion vector at the center of the block, regardless of the source
// of the base warp model.
//
// * If the mode is NEARMV, then we need to consider the source of the
// base params and the motion vector carefully:
//
// * If we're extending from a neighboring block, then the predicted
// motion vector (in mbmi->mv[0]) does *not* match the prediction
// from the base warp model. This because the predicted MV is
// set to the MV at the center of the *neighboring* block, to avoid
// having motion vector prediction depend on the construction of the
// neighbor's warp model.
// So in this case, we want to re-calculate the motion vector at
// the center of this block from the neighbor's warp model. This is
// okay, and does not introduce a similar parsing dependency, because
// this only affects the resulting warp parameters, not any of the syntax.
//
// * However, if we're not extending from a neighboring block, then we
// use the global warp as a base. In this case, taking the predicted
// MV from whatever ref block we used, is probably better than using the
// predicted MV from the global model, because if we wanted the latter
// then we would have used the GLOBALMV mode.
