Subject: evas: disable unecessary lock when not using evas_render2
X-Git-Tag: submit/sandbox/upgrade/efl120/20180319.053334~1722
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5017f06a728cbfb33f911acd867ff9b4bf81515f;p=platform%2Fupstream%2Fefl.git

evas: disable unecessary lock when not using evas_render2

Calling this lock for no good reason result in a 2% slow down. Easy
enough to disable as we do not use evas_render2 at all. Might be
something to consider if we ever develop evas_render2 further.
