391 // Draw Context

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