                     33:     This routine gets called when GDI needs to synchronize with the

                     35:     This routine waits for the accelerator to be idle before returning.

                     40:     prcl   - rectangle where GDI wants to write to. Since the driver
                     41:              doesn't keep track of where the accelerator is actually
