Do we need a SetNeedsPushProperties with this?

[hendrikw, 2015/03/19 23:34:33]

No, the only time we need a push with this is when we're calling it from within
the push already.

Sorry, so this is intentional that viewport size may be out of date on the
compositor thread for certain layers?

This patch is certainly simplest, but this is also not a forward-looking
solution for slimming paint.  https://codereview.chromium.org/1013273003 is a
lot more in line with what we'll need in the future, so it feels like we should
just do that instead, even if it's more code.
