Short description of error

Spent an hour wondering why viewport for render was not working properly for cycles (no rendering). This was due to the pause button being unknowingly activated. With it hiding in the top right corner and not changing to a play button it was hard to realize this was the issue. I suggest having it change to a play button to make it just a little more apparent to new users like myself.

Exact steps for others to reproduce the error
[Please describe the exact steps needed to reproduce the issue]
[Based on the default startup or an attached .blend file (as simple as possible)]
NA happens with one button click

Could be nicer, agree, not a real bug though (btw., you should also see a text "Rendering Paused" in the top left corner if you have Text Info overlay showing...).

@William Reynish (billreynish): Does this catch your eye? Do you think this should go in?

Will close this anyways, since this is not really a bug.
