It's possible for our code to think that the user wants to pan the
profile before realizing that the user actually is making a pinch
gesture. In that case the profile could get stuck in semi-transparent
mode. This prevents that from happening by explicitly resetting the
opacity to 1.0 when we start a pinch.
