- keep screen-to-map-plane projection in Matrices so that this stays consistent for a frame
- dont modify map-plane coord array that is passed to ScanBox
JobQueue now belongs to TileManager instead of TileLayer
release TileSet after rendering
add MapView.clearMap() -> clear all previous map state in Layers on next onUpate
- now labels are cleared properly when the or mapdb changes.
- getTileSet now requires a TileSet instance as input
use own UTF8Decoder
always internalize tag key Strings
add comments
no need to internalize these
