Testing the BitBLT Active Status after starting a new BitBLT is simpler and less prone to
errors.
To test after each BitBLT operation, perform the following.
1. Program and start the blit engine.
2. Wait for the current BitBLT operation to finish -- Poll the BitBLT Active Status bit
(REG[100h] bit) until it returns a 0.
3. Continue the program.
