106 * From the Microsoft docs:
107 * "If flat scroll bars haven't been initialized for the
108 * window, the flat scroll bar APIs will defer to the corresponding
109 * standard APIs. This allows the developer to turn flat scroll
110 * bars on and off without having to write conditional code."
112 * So, if we just call the standard functions until we implement
113 * the flat scroll bar functions, flat scroll bars will show up and
114 * behave properly, as though they had simply not been setup to
115 * have flat properties.
