Remarks
Returns a value between 0 and 1 on how far along the back gesture is. This value is driven by the horizontal location of the touch point, and should be used as the fraction to seek the predictive back animation with. Specifically, <ol> <li>The progress is 0 when the touch is at the starting edge of the screen (left or right), and animation should seek to its start state. <li>The progress is approximately 1 when the touch is at the opposite side of the screen, and animation should seek to its end state. Exact end value may vary depending on screen size. </ol> <li> After the gesture finishes in cancel state, this method keeps getting invoked until the progress value animates back to 0. </ol> In-between locations are linearly interpolated based on horizontal distance from the starting edge and smooth clamped to 1 when the distance exceeds a system-wide threshold.
