Can you remove all "#if defined(OS_ANDROID)" from the renderer side?  I prefer
for renderer-side code to be compiled cross-platform unless there is a strong
reason otherwise.  One big advantage is that then you can run its unit tests on
Linux as well.  (Most developers find it hard/slow to locally run unit tests on
Android.)
