Subject: [PATCH 21/40] ARM: NEON optimization for bilinear scaled 'src_0565_0565'
Benchmark on ARM Cortex-A8 r2p2 @1GHz, 32-bit LPDDR @200MHz:
Microbenchmark (scaling 2000x2000 image with scale factor close to 1x):
before: op=1, src=10020565, dst=10020565, speed=3.30 MPix/s
after: op=1, src=10020565, dst=10020565, speed=32.29 MPix/s
