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