From e3597c6af7ff3b8bbe863fe74f7fdc17e20767e5 Mon Sep 17 00:00:00 2001 From: Dmitry Kovalev Date: Mon, 7 Oct 2013 13:55:56 -0700 Subject: Moving all scan/iscan code into separate vp9_scan.{h, c} files. Now we have entropy code separate from scan/iscan code. The next step in future is to move iscan code from common part to the encoder.
