Flicker free means no full refresh of pages for screen displaying in monitoring. Only individual cells should be refreshed.
Flicker free screen should deliver exactly the same look&feel as screens in Zabbix 2.0. Be careful when implementing support of URLs!
All cells must be refreshed individually and absolutely instantly, no flickers are allowed. Even if we have 100x100 screen, there will be no flickering during refresh of individual cells.
Time navigator will not cause page reload.
New code base could be reused in the future to make screen elements embeddable into Dashboard.
Logic and presentation must be separated for displaying cells of different types. Each cell-type must use separate file(s) for presentation.
