/*! \addtogroup utilities

  FLTK provides some functions that it uses internally that are
  necessary for portablity, or convienent for writing code.  These are
  \e not in the fltk:: namespace and do not have "fl_" in their names,
  because in theory they should not be part of fltk, but instead
  provided by the system.

/*! Does strcpy(filename_ext(buf), ext ? ext : ""). Returns \a buf.

  \a ext is usually a desired extension, starting with period, such
  as ".jpg". If it is null it acts like "".

  If there is no period in \a buf, \a ext is concatenated.

  Otherwise the last period is replaced with the first character of
  \a ext and the rest copied there.
