From: Siarhei Siamashka <siarhei.siamashka at nokia.com>

The following patches reorganize nearest neighbor scaling fast
path macros to allow SIMD optimizations.

SSE2 optimization for scaled over_8888_8888 operation with
nearest filter is provided as an example (this operation
becomes more than 2x faster).

Siarhei Siamashka (3):
  Nearest scaling fast path macro moved to header file and split into
  SSE2 optimizations for scaled over_8888_8888 with nearest filter
  Use more unrolling for scaled src_0565_0656 with nearest filter
