## Detailed Description

The QWSPointerCalibrationData class is a container for data used in calibration of a mouse handler.

QWSPointerCalibrationData stores device and screen coordinates in the devPoints and screenPoints variables, respectively.

A calibration program should create an instance of this class, fill the devPoints and screenPoints variables with its device and screen coordinates, and pass the QWSPointerCalibrationData object to an instance of the QWSMouseHandler class using the QWSMouseHandler::calibrate() function.
