Requesting documentation for VertexBuffer

[CrowsOfWar]

Hey there,

I was writing some entity-rendering code tonight and was having a bit of trouble understanding the new(ish) VertexBuffer class.

While I have a better grip on it now, I'd love for someone with a deeper knowledge of MC code to actually explain it on the documentation. For example, I don't know what each VertexFormat does. There is basically no useful javadoc in the code :(

Thanks!
