f47e1d4995 [libpng16] Eliminated PNG_NO_INTEL_SSE_3BPP which was just for testing. 2016-04-05 12:16:27 -05:00

8f506d3257 SSE filter speed improvements for bpp=3. 
- memcpy-free implementations of load3() / store3().
    These should have less variance compiler to compiler.

    - call load3() only when needed at the end of a scanline.
    In the middle, we can use the faster load4(), ignoring that byte.
