- Previously, we clamped the progress to 1 when reaching mTransitionDragLength. Now, we allow dragging all the way to the top of the screen, and store this new top progress in mDragLengthFactor (> 1f). - Because the launcher animation controller is inherently bound to a progress between 0 and 1, we have to do a bit of trickery involving interpolators. Specifically, we normalize the progress to 0 to 1 by dividing by mDragLengthFactor, but then we set the interpolators to multiply their progress by mDragLengthFactor. The result is that the animation progress appears to go from 0 to mDragLengthFactor, just like the window progress. - To avoid scaling too small, we start interpolating the progress at a certain point, ending at a specified max progress when reaching the top of the screen.
