Use region sampling to properly tint the bubble expanded view handle
* Create a RegionSamplingHelper when the taskview is shown
* Sampling only occurs while the view is visible and not being
dragged
* RegionSamplingHelper is destroyed when the task is removed or the
view is detached
* Added tests for BubbleBarExpandedView verifying when the helper
is started / stopped appropriately
* Don't animate the handle color if it's the same
Minor unrelated change:
* Apply the caption insets when the TaskView is created, not on
every layout pass
Test: atest BubbleBarExpandedViewTest
Test: manual - open a bubble, check that the handle is the right
color, do something in the bubble that would change
the handle color (e.g. put maps in a bubble and open
an image of a location, check that handle color changes
appropriately)
- repeat above after dragging the bubble to the other
side
- repeat above after expanding / collapsing the bubble
