The rounding and arithmetic is not the same as previously, to prevent overflow cases for large upscale factors. We still rely on 32b x 32b -> 64b multiplies. Raised the fixed-point precision to 32b so that we have some nice shifts from epi64 to epi32. Changed rescaler_t type to 'uint32_t' in order to squeeze in all the precision required. The MIPS code has been disabled because it's now out-of-sync. Will be fixed in a subsequent CL when the dust settles. ~30-35% faster Change-Id: I32e4ddc00933f1b1aa3463403086199fd5dad07b
