Throttle the touch move events sent to the renderer.

Throttle the touch move events sent to the renderer.

Sending too many touch move events too quickly can overwhelm the renderer. So
wait for an ACK from the renderer before sending out an event to maintain the
renderer at just the right amount of whelm.

The renderer already does the right thing, so it doesn't need to be updated.

why do you need both me and Scott?  I'm not familiar with this code.

Ah. I added you for OWNERS, but now I see that Scott is in OWNERS too. My bad!

De we need the ifdefs? If you're not on a touch device will we get any of these
events?
