World
This class provides a base window controller with required properties and methods which subclasses may inherit from to create custom window controllers for controlling the globe via user interaction.
Event listeners are plain (Event) -> Unit functions: Kotlin/Wasm cannot implement the external org.w3c.dom.events.EventListener, so the whole input pipeline uses function values instead.

Properties
Inertial pan animator. Each platform's createFlingScheduler supplies the per-frame clock. The per-frame action dispatches by projection: 2D uses incremental projected-meters math, 3D uses great-circle radians. Picking the right one matters because Mercator metersPerPixel diverges from the 3D radians-on-a-sphere formula away from the equator.
Shared anchor for pinch / rotate / wheel handlers. Lazy because engine may not be initialized yet at controller-construction time.
Trailing-window velocity tracker used to seed fling on gesture release.
