 108  *      standard APIs.  This allows the developer to turn flat scroll
 109  *      bars on and off without having to write conditional code."
 110  *
 111  *      So, if we just call the standard functions until we implement
 112  *      the flat scroll bar functions, flat scroll bars will show up and
 113  *      behave properly, as though they had simply not been setup to
 114  *      have flat properties.
