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