+The class encapsulates non-visual scales.
+She is utilized by Axis and also collaborates closely with AutoScaler.
+A Scale allows control over all aspects of tic generation including
+arbitrary transformations of tic values into corresponding strings.
+The strings contain what eventually will be shown as tic labels.\n
+Standard linear and logarithmic scales have been integrated yet into the Axis
+interface. User-defined axes can be derived from Scale, LinearScale et al.
