I'm writing up a 2D graphics tutorial and although I've used OT's to get
my stuff working, it was all straight from the examples. Closer
inspection revealed that an OT is just an array of OT_TAGS, which are
just 32 bit wide bit fields:

unsigned p:24;
unsigned num:8;

So what I want to know is:

What is p? What is num?

How do they specify which GPU packets get sent, and in what order? How
is the linked list maintained?

How are they affected by 2D graphics?
