* @par Description
* This routine performs motion compensation of an inter mb. When the inter
* mb mode is P16x16, there is no need to copy 16x16 unit from reference buffer
* to pred buffer. In this case the function returns pointer and stride of the
* ref. buffer and this info is used in place of pred buffer else where.
* In other cases, the pred buffer is populated via copy / filtering + copy
* (q pel cases) and returned.
