Needs a lot of cleanup. Data has been de-duplicated, and where identical copies existed, one of them has been replaced with a symlink. Some files have been excluded, such as binaries, installers and debug dumps. Some of that may still be present.

// This is an example script that demonstrates use of the Camera class's lookAt(), keepLookingAt(), and stopLookingAt()
|
|
// features.
|
|
//
|
|
// To use the script, click on a voxel, and the camera will switch into independent mode and fix it's lookAt on the point
|
|
// on the face of the voxel that you clicked. Click again and it will stop looking at that point. While in this fixed mode
|
|
// you can use the arrow keys to change the position of the camera.
