Linear, logarithmic and exponential scaling of data for the WorldCanvas.
Prerequisite
Etymology
WCPowerScaleHandler : WorldCanvas Power Scale Handler
Synopsis
The WCPowerScaleHandler is an implementation of the WCDataScaleHandler that uses linear, logarithmic or exponential scaling to transform (probably non-discrete) input data into discrete output values in the range 0 to a settable maximum. Typically, this maximum would be set to the available number of colorcells minus one, for indexed raster drawing, or to a large integer (say 1000000) for use in color cube raster drawing. In the latter case, the output is then divided by the chosen large number in order to provide values in the range 0 to 1.
Motivation
This class is motivated by the need to provide the most common data scaling requirements to the user.
