Merge main into fix/ocg-auto-state-view; renumber its patch to (103)

Browse Source 
Main took hayro-interpret patch (76) for non-embedded Arial and Times New Roman
CIDs, so the View auto state becomes patch (103) in the ledger and the code
comments. The view.layers-panel note no longer lists the Print event's auto
state as missing: main applies it when printing (print.print-ready-pdf).
