-// For print preview, a print preview (PP) tab is linked with the initiator tab
-// that initiated the printing operation. If the tab initiates a second
-// printing operation while the first print preview tab is still open, that PP
-// tab is focused/activated. There may be more than one PP tab open. There is a
-// 1:1 relationship between PP tabs and initiating tabs. This class manages PP
-// tabs and initiator tabs.
