This shows how to create an infiniminer or minecraft like world.
Features of this tutorial are:

- World is subdivided in chunks, which can be created and updated on the fly.
- Each chunk has an associated VBO.
- Removes block faces which are not visible.
- Merges adjacent block faces to reduce the number of vertices to draw.
- Very simpe transparency using the discard keyword in the fragment shader.
- Uses only 4 bytes per vertex (including texture information).
- Performs its own texture wrapping in the fragment shader.
