I think here you'll need to do conditional compilation to make NaCl use
CreateImageDataSimple?

This also brings up the question of how the plugin draws frames. Does it use
what it's given, or does it have to create a new one? If it's creating a new
one, in the trusted case, it will be creating & sending "platform" image datas,
while it is receiving "simple" ones. I don't actually see any harm in that, but
it is a little odd.

Done.

Hopefully it will be a NaCl plugin that actually ships.
