381 // Draw Context
382 // The api thread sets up a draw context that exists for the life of the draw.

436 // Draw Context Ring
437 // Each draw needs its own state in order to support mulitple draws in flight across multiple threads.
438 // We maintain N draw contexts configured as a ring. The size of the ring limits the maximum number
442 // 1. State - When an application first sets state we'll request a new draw context to use.
443 // a. If there are no available draw contexts then we'll have to wait until one becomes free.
446 // 2. Draw - Creates submits a work item that is associated with current draw context.
449 // 3. State - When an applications sets state after draw
451 // b. State is copied from prev draw context to current.
454 DRAW_CONTEXT *pCurDrawContext; // This points to DC entry in ring for an unsubmitted draw.
460 // Draw State Ring
461 // When draw are very large (lots of primitives) then the API thread will break these up.
463 // in the Draw Context (DC) we instead store it in a Draw State (DS). This allows multiple DCs
