I think these can be const

Thanks for the feedback @addaleax. Yes, they could be. FWIW when I first PRed those changes there was no const in that file and after the changes were first merged in #3888 and reverted in #6680 I didn't want to rock the boat with anything other than changes that had already been previously +1ed (since the original PR had a hard enough time landing). Also FWIW there's a bunch of other var in the file that could be const. The specific vars you commented on are each only referenced once, so honestly probably the best thing is to just eliminate those bindings and use opts where those are referenced. The same probably goes for at least some of the vars in render().

Let me know if you want me to make a change either way.
