• IGeneratorVisualizer and IVisualizerType now extend ISyncRegistries which has #additionalSynchronization and #elementCodecForRegistry, allowing GVs to specify how a registry is synced
  • #elementCodecForRegistry has been changed to operate similarly to #additionalSynchronization to avoid having to deal with type casts
  • Update ClimateFeatureCache#codecForRegistry to handle the #elementCodecForRegistry changes
• Add ITFCGeneratorVisualizer which syncs TFC's rock settings registry and is the base of the built-in grid and chunk scale GVs
