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