+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]
