Android 10 seems to expect a prerotated/transformed swap chain for optimal presentation. For now, until we implement that, just ignore the hint.
See: https://twitter.com/Themaister/status/1207062674011574273
This was causing us to recreate the swap chain every frame, with an identity pretransform which would return suboptimal for the next presentation, repeat. Hence performance loss, since it's not cheap. I'm surprised the hit wasn't higher to be honest.
