Detailed Description

This class manages the HoverPoints in the transfer function. Points can be added, moved and deleted. Points can also be locked to a certain axis. A linear curve or a spline curve can be drawn as a connection between the points. Points are sorted automatically when added. This class was taken from the Qt Gradients examples and modified to our own needs.
