Tutorials/Update LWJGL (Legacy)

What is LWJGL?
LWJGL is the LightWeight Java Game Library. Essentially, it is what Minecraft uses for graphics, sound, and input. The latest version of LWJGL is 2.9.0.

Mojang currently ships LWJGL 2.4.2 for Minecraft release 1.5.1 and below. Mojang plans to ship newer versions of LWJGL for the upcoming Minecraft release of 1.6.

Why update?

 * Updating will fix some input bugs where keys seem to get stuck if you click at the same time. It also removes the "ghost" mouse pointer clicking.
 * Some users report a performance increase upon updating.
 * This can also potentially fix some issues regarding sound not working/cutting out.
 * It has been reported to fix intermittent crashes on Windows.
 * It has also been known to resolve the "cannot get JAWT interface" error for Mac users using Java 7.
