useDevicePixels seems to be interpreted badly (v9.0)

[xinaesthete]

It seems that with a window.devicePixelRatio === 2, luma renders into the lower-left corner of the canvas unless you explicitly set for example WebGLDevice.create({ useDevicePixels: false });.

I haven't tested with other kinds of devices etc.

@xinaesthete thanks for reporting.

Is this on master or 9.0? There has been a fix related to rendering in lower-left corner on master. Probably one of the below PRs, might be possible to backport and put up a PR on 9.0-release.

This is on 9.0, I meant to mention that.
