## Displays a selection scale (range widget) window.
## Allows the user to choose a parameter within the set ranges, and sets
## default value, and step sizes.
## The variable @var{title} sets the title of the window.
## The variable @var{text} sets the label of the range widget.
## The optional arguments @var{value}, @var{minval},@var{maxval},
## @var{step}, @var{print_partial}, and @var{hideval}.
## The range widget can be used to select anywhere from @var{minval} to
## @var{maxval} values in increments of @var{step}. The variable
## @var{print_partial} and @var{hideval} are boolean flags to partial
## and hidden views of the value on the range widget.
## The first 3 parameters are essential, while the remaining parameters
## @var{minval}, @var{maxval},@var{step},@var{print_partial},@var{hideval} if
## not specified take on default values of 0,100,1,false,false
## respectively.
