Subject: Reduce memory footprint for CLPF encoding.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a8af9126fbddabe842319856dc39bf5462145eec;p=libvpx

Reduce memory footprint for CLPF encoding.

Use in-place filtering, like in the decoder
(see eb5794da1659f87597291d84c2fbdfd89280065d).
