Class: RasterTileset2D
Defined in: packages/deck.gl-raster/src/raster-tileset/raster-tileset-2d.ts:150
A generic tileset implementation organized according to the OGC TileMatrixSet specification.
Handles tile lifecycle, caching, and viewport-based loading.

Get tile indices visible in viewport Uses frustum culling similar to OSM implementation
Overviews follow TileMatrixSet ordering: index 0 = coarsest, higher = finer
minZoom and maxZoom gate against viewport.zoom (not the tileset
z-index, which is an overview level in our descriptor). When the
viewport zoom is outside these bounds this method returns an empty
list — no new tile fetches, and because deck.gl's updateTileStates
marks unselected cached tiles invisible, no rendering either.
visibleMinZoom / visibleMaxZoom (deck.gl 9.3+) are deliberately
not honored: their documented "fetch but don't render" semantic
requires a notion of clamping to a coarser z, which doesn't
generalize to descriptors with sparse or single overviews. See
dev-docs/zoom-terminology.md for the rationale.
