+Параметры:
+  * eax = 34 - номер функции
+  * ebx = x-координата (относительно экрана)
+  * ecx = y-координата (относительно экрана)
+
+Возвращаемое значение:
+  * eax = 0x000000XX - точка принадлежит слоту окна N
+    При некорректных значениях ebx и ecx функция возвращает 0
+  * Функция берет значения из области [_WinMapAddress]
