- New importer, needs restart to switch but it's a limitation of Godot
- Might blow up if the scene spans a really big area, may be optimized in the future.
- The scene importer remains the default choice
- Promoted some ints to 64-bit to avoid oveflowing with large volumes or distances
- Handle a few cases of malloc failure
This was mainly apparent when optimization was enabled.
It caused outputs to be left uninitialized and either work by chance
or provide the wrong values.
