* \param[in] cpi Top-level encoder structure.

* \param[in] x Pointer to struc holding all the data for
* the current macroblock.
* \param[in] bsize Current block size.
* \param[in] tmp_dst A temporary prediction buffer to hold a

* \param[in,out] orig_dst A prediction buffer to hold a computed
* prediction. This will eventually hold the
* final prediction, and the tmp_dst info will
* be copied here.
* \param[in,out] rd The RD cost associated with the selected
* interpolation filter parameters.
* \param[in,out] switchable_rate The rate associated with using a SWITCHABLE
* filter mode.
* \param[in,out] skip_build_pred Indicates whether or not to build the inter
* predictor. If this is 0, the inter predictor
* has already been built and thus we can avoid
* repeating computation.
* \param[in] args HandleInterModeArgs struct holding

* struct for a description of each member.
* \param[in] ref_best_rd Best RD found so far for this block.
* It is used for early termination of this

*
* \return Returns INT64_MAX if the filter parameters are invalid and the
