isSinglePixelPadding

This checks if the camera padding is focused on a single point. If so, it indicates that the camera is in following mode, centered on the user location indicator. This is the only state when scale gestures can be executed without disrupting tracking, or when camera and puck can be fully synchronized.

This check is needed because there are instances where the camera is in following mode but not focused on a specific pixel, such as when FollowingFrameOptions.maximizeViewableGeometryWhenPitchZero is enabled. In these cases, tracking must be interrupted when user zooms in because the camera center is not focused on the user location indicator.
