 * These flags indicate a presentation blt (i.e. a blt

 * The "end" of the presentation blt is indicated, since the
 * blt may be clipped, in which case the runtime will call the driver with 
 * several blts. All blts (even if not clipped) are tagged with DDBLT_PRESENTATION
 * and the last (even if not clipped) additionally with DDBLT_LAST_PRESENTATION.
 * Thus the true rule is that the driver must not schedule a DDBLT_PRESENTATION
 * blt if there are 3 or more DDBLT_PRESENTLAST blts in the hardware pipe.
 * If there are such blts in the pipe, the driver should return DDERR_WASSTILLDRAWING
 * until the oldest queued DDBLT_LAST_PRESENTATION blts has been retired (i.e. the
 * pixels have been actually written to the primary surface). Once the oldest blt
 * has been retired, the driver is free to schedule the current blt.
 * The goal is to provide a mechanism whereby the device's hardware queue never
 * gets more than 3 frames ahead of the frames being generated by the application.
 * When excessive queueing occurs, applications become unusable because the application
 * visibly lags user input, and such problems make windowed interactive applications impossible.
 * Some drivers may not have sufficient knowledge of their hardware's FIFO to know
 * when a certain blt has been retired. Such drivers should code cautiously, and 
 * simply not allow any frames to be queued at all. DDBLT_LAST_PRESENTATION should cause
 * such drivers to return DDERR_WASSTILLDRAWING until the accelerator is completely
 * finished- exactly as if the application had called Lock on the source surface
 * before calling Blt. 
 * In other words, the driver is allowed and encouraged to 
 * generate as much latency as it can, but never more than 3 frames worth.
 * Implementation detail: Drivers should count blts against the SOURCE surface, not
 * against the primary surface. This enables multiple parallel windowed application
 * to function more optimally.
 * This flag is passed only to DX8 or higher drivers.
 *
 * APPLICATIONS DO NOT SET THESE FLAGS. THEY ARE SET BY THE DIRECTDRAW RUNTIME.
