125 * From the Microsoft docs:
126 * "If flat scroll bars haven't been initialized for the
127 * window, the flat scroll bar APIs will defer to the corresponding
128 * standard APIs. This allows the developer to turn flat scroll
129 * bars on and off without having to write conditional code."
131 * So, if we just call the standard functions until we implement
132 * the flat scroll bar functions, flat scroll bars will show up and
133 * behave properly, as though they had simply not been setup to
134 * have flat properties.
