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