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