| ===================== Function 15, subfunction 9 ===================== |
| ============= Redraws a rectangular part of the background =========== |
| ====================================================================== |
| Parameters: |
| * eax = 15 - function number |
| * ebx = 9 - subfunction number |
| * ecx = [left]*65536 + [right] |
| * edx = [top]*65536 + [bottom] |
