  91  *      From the Microsoft docs:
  92  *      "If flat scroll bars haven't been initialized for the
  93  *      window, the flat scroll bar APIs will defer to the corresponding
  94  *      standard APIs.  This allows the developer to turn flat scroll
  95  *      bars on and off without having to write conditional code."
  96  *
  97  *      So, if we just call the standard functions until we implement
  98  *      the flat scroll bar functions, flat scroll bars will show up and
  99  *      behave properly, as though they had simply not been setup to
 100  *      have flat properties.
