Detailed Description

brief Manages property links between differerent displays.

Property links can be ranges, color sequences and other parameters.

The intelligence on what can be linked lies in the subclasses of DisplayPropertyLink.

Displays that are able to link properties to must inherit DisplayPropertyHolder and in addition must be added to the DisplayLinkManager.

To create a link from a certain DisplayPropertyHolder, DisplayLinkManager::createPossibleLinks should be called. This fills an ObjectSet<DisplayPropertyLink>&, and one or more links in that set may be enabled by calling DisplayPropertyHolder::addDisplayPropertyLink().

The link is removed by calling DisplayPropertyHolder::removeDisplayPropertyLink().
