- VoxelGenerator no longer inherit VoxelStream
- VoxelStream is now more focused on files
- Nodes have separate stream and generator properties
- Generators use 2 dedicated threads instead of sharing a single one with streams
- TODO Image.lock() is problematic for multithreading
- TODO Voxel graph can cause RWLock contention if edited while it runs
- TODO Saving generator output no longer works, need to put it back
- Added a global file locker so threads can synchronize when accessing files
- Added mutexes to serialize access to file streams (i.e to call in series)
- VoxelStream API now expects implementations to be thread-safe
- Did some logic/data separation in RegionFile in case we need an
in-memory implementation, however I might just use SQLite in the
future instead
VoxelLodTerrain's block requests were being cancelled constantly.
This commit also contains precision improvement for cancelling
block requests based on distance, which originally was an attempt to
"properly" fix the problem with VoxelLodTerrain, but it didnt fully
worked for that node.
I left it anyways, maybe it will change in the future once a
proper fix is figured out.
