added barriers against zero valued overlayControlData.individualScale (#2721)

Some recent change already in master caused some @android users to reach a state in which they were missing individualScale value to some input overlay controls.

I was affected, and some fella in #tester-chat even shared a video.

These 3 new barriers makes eden ignore individualScales if they're zeroed (feeding 1f instead), avoiding the crash, and allowing users to further adjust controls scales.

Safe and functional.
