can you group these two use_ with the other use_ above? maybe make them all
const?

[danakj, 2017/02/16 18:54:19]

can be const

[halliwell, 2017/02/23 18:01:46]

I grouped them.  Making them all const is a bit verbose to access context caps
in initializer list.  Could fix that by grouping in a struct and passing
gpu::Capabilities to its constructor but maybe best left to another CL?

Ah, right, good points, what u did seems good
