* Move clipping tests from inside to outside loops
* Let sizex and sizey to clpf_block() be the clipped block size rather
than both just bs
* Make fallback tests to C more accurate

Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.
This reduces the cycles spent in the filter to ~75%.
