// - State switching optimizations -----------------------------------

/**
 * The goal is to reduce device state switching as much as possible.
 * This means: don't reset the texture if not needed, don't change
 * the texture stage states unless necessary.
 * For this we need to track the current device state. So each operation
 * supplies its own operation type to BeginScene, which updates the state
 * as necessary.
 *
 * Another optimization is to use a single vertex format for
 * all primitives.
 *
 * See D3DContext::UpdateState() and D3DContext::BeginScene() for
 * more information.
