Coalesce all uploaded chunk textures by region, meaning we need to do 1-4 texture uploads instead of 225.
Snapshot the region data arrays for thread-safety, but write the BufferedImage data in a separate thread. Snapshotting is around 30x faster than image building, so this should help a lot with FPS spikes during image writing, especially on slower systems.
