you can (eventually) remove this based on today's discussion

[Fady Samuel, 2015/08/06 16:48:24]

Done.

[rjkroege, 2015/08/06 00:16:22]

why do we have a gpu service? is it still necessary in the revised ui process
world

[Fady Samuel, 2015/08/06 16:48:24]

I'm not sure yet. html_viewers still need a Command Buffer, right now.

[rjkroege, 2015/08/06 22:09:02]

not same. Yes, html_viewers need a CommandBuffer. But do they need to implement
GPU except to handle webGL? Can you put a TODO here (assigned to me if you like)
to wonder about this.
