Create larger worlds by having a single-volume sub-view

Create larger worlds by chunking them, and allow the camera to navigate between 
chunks. When the user creates a large world (i.e. 1k x 1k), only render a 
volume of 64 x 64 (this can change if the user has a better graphics card). 
This volume can only be positioned between (0, 0, 0) to (world width - 64, 
world length - 64, world depth - 64).

The camera should thus have a static distance and no translation. When moving 
to any direction, the camera should not move locally (relative to the 
view-volume), though should move in the global space.
