Description
Motivation
Some users may experience blank or missing tiles during the camera animation due to a slow or unstable internet connection.
Design
We can improve the perceived performance of camera animations by kicking off some future tile requests ahead. E.g., requesting the parent tiles for the last transform or tiles with the lowest zoom level along the animation path.
First, this was introduced in #11328 and then dropped in #11357 after discovering some breaking changes.

Research direction
Start by reviewing the prior implementations in #11328 and #11357, especially why the change was dropped after breaking changes were found. The work is done when camera animations prefetch appropriate future or parent tiles without reintroducing those breaking changes or leaving blank tiles.
