Some improvements to home to overview transition for 0 button mode

- Peek in overview further, and with more overshoot
- Fade out and scale down workspace faster while swiping up
- Scale and translate workspace slower when letting go to enter
  overview (so it doesn't zoom out at warp speed)
- Fade in all apps shelf sooner
