Finally free

Browse source 
- Free from mojmath, have to flip many matrix field accesses.
- Free the memory allocated in model cache.
  - Shout out to pepper's DebugMemoryBlock telling me *exactly* where a
    leak was from.
- Instancing and batching seem to mostly work, indirect appears to be
  rendering instances in the wrong places, though they are culled from
  their real location.
