This fixes every case where virtual and SK_OVERRIDE were on the same line, which should be the bulk of cases. We'll have to manually clean up the rest over time unless I level up in regexes. for f in (find . -type f); perl -p -i -e 's/virtual (.*)SK_OVERRIDE/\1SK_OVERRIDE/g' $f; end BUG=skia: Review URL: https://codereview.chromium.org/806653007
