05416e2d9a Box filter for YUV use rows with accumulation buffer for better memory behavior. The old code would do columns accumulated into registers, and then store the result once. This was slow from a memory point of view. The new code does a row of source at a time, updating an accumulation buffer every row. The accumulation buffer is small, and should fit cache. Before each accumulation of N rows, the buffer needs to be reset to zero. If the memset is a bottleneck, it would be faster to do the first row without an add, storing to the accumulation buffer, and then add for the remaining rows.

4e78b8dc2e scale to 3/4 or 3/8 with odd width destinations efficiently. previously if width was not multiple of what the simd loop would do (24), scaling would fall back on slower C code. This change allows SIMD to be used for most of the scaling and C for the remainder, improving efficiency.

ca308327d2 Remove unaligned functions, since most function support unaligned memory now. This reduces complexity and improves performance for unaligned cases because C code can be avoided, and overhead is less.
