aruslan@, is there an easy way to get the browser window bounds on Android?

Risk team says it's not necessary (not particularly useful on mobile), so if
not, we can just skip over it.

[aruslan, 2015/02/10 00:18:21]

You might use the size of the display with and without window decorations using
DeviceDisplayInfo().GetPhysicalDisplayHeight() etc.

It wouldn't work in all cases (e.g. in the case of multi-window devices etc),
but it's a good first approximation and it's an easy way.

+  // contents).

+#if !defined(OS_ANDROID)
