We should avoid this cast. One way would be by having a shared
StreamTextureFactoryImpl per RenderThreadImpl, then RTImpl can create it when it
creates ContextProviderCommandBuffer. But that needs pulling |frame_id| out of
STFImpl's constructor (and maybe passing it to WMPAndroid instead so that can
pass it to EstablishPeer?).

Ugh, sorry, looks like this is all not so straightforward to untangle and make
nicer.

untangle and make
I will check this.
