can we remove virtual since it it not overriding an interface any more.

[perkj_chrome, 2014/03/04 10:44:51]

Done.

+                        const ConstraintsCallback& callback);

[Ronghua Wu (Left Chromium), 2014/03/04 01:04:11]

why remove OVERRIDE but not virtual?

[perkj_chrome, 2014/03/04 10:44:51]

Done.
