- Moved colors to final in TaskbarViewController (since controllers are
recreated on theme change)
- Clarified some variable names
- Animate from progress 1 to 0 instead of vice versa, since 0
corresponds to launcher's theme icon color which is what the alignment
animation is going towards
Test: in gesture nav with dark themed icons in hotseat, go to overview
and ensure smooth transition to ligher themed background; return home
and ensure reverse transition
Flag: none
