 110  *      From the Microsoft docs:

 113  *      standard APIs.  This allows the developer to turn flat scroll
 114  *      bars on and off without having to write conditional code."
 115  *
 116  *      So, if we just call the standard functions until we implement
 117  *      the flat scroll bar functions, flat scroll bars will show up and
 118  *      behave properly, as though they had simply not been setup to
 119  *      have flat properties.
