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