[DO NOT MERGE] Fix some visual jumps when swiping home
All caused by running the transform progress from 0 to 1 instead of
starting at whatever the progress was before ending the gesture, e.g.:
- When swiping to home without animating into an icon, the corner radius
was set back to the window corner radius.
- Before this change, the clip didn't update throughout the animation,
making the window slightly bigger than the floating icon view; after
this change, the clip jumped to show the insets again before clipping
back down during the home animation.
