| ========= Function 34 - who owner the pixel on the screen. =========== |
| ====================================================================== |
| Parameters: |
| * eax = 34 - function number |
| * ebx = x-coordinate (relative to the display) |
| * ecx = y-coordinate (relative to the display) |
| Returned value: |
| * eax = 0x000000XX - owner of pixel the slot window N |
| If incorrect values ebx and ecx then function returns 0 |
| * The function takes the value from the area [_WinMapAddress] |
