- along the lines of the SSE chroma upsampling. Total speedup is ~30%. 4% speed loss on YuvToRgbXX conversion using tables instead of 14-bit fixed precision. TODO(later): investigate, and compare to x86. see http://code.google.com/p/webp/issues/detail?id=134 Change-Id: Idc2261037cd13b4553ca20ecc4c4007099c37009
