Fornax

What Changed:

• page the block atlas automatically instead of behind a flag
  • the flag was off by default, so a 512x pack just failed to load with "try a lower resolution resourcepack" and nothing pointing at the switch.
  • paging only ever runs when the alternative is that failure, so there was nothing for a setting to choose.
• drop labPBR sidecars from every atlas, not just blocks.
  • entity and banner atlases were carrying 786 MB of maps nothing samples.
• size the sprite-bounds grid to the pack.
  • a coarse grid forces a coarse placement pitch and wastes most of an overflow page. packs read it through fornax_spriteGridCell now instead of hardcoding the number.
• cap overflow pages by available memory rather than a fixed count, so a pack that will not fit refuses at load instead of swapping the machine.
• log the sprite-bounds grid size when it rebuilds the grid is resized per pack now, and nothing said what it ended up at, so there was no way to tell whether a big pack's grid was released.
