Maybe use Matrix4f.unprojectRay/unprojectInvRay() in chapter 23 #21

Since version 1.8.0 (released on June 3, 2016) JOML's Matrix4f class can unproject from window coordinates via unprojectRay() and unprojectInvRay(). The MouseBoxSelectionDetector.selectGameItem() can be simplified then.

I can mention that in the book, but maybe it's a good idea to see how the process is done.
