when there is no view (i.e. default reader view fit) then we can save 
bytes by using page references as they don't contain dimensions

most of the needed code is there; i only need to figure out how to do it 
efficient (as i don't want bloated tuc file due to rather useless extra 
references) so i'll have a look at it

not even acrobat always complies/complied with the standard (or 
implemented it) .. widgets are the worst

i'm surprised that you can run luatex/mkiv on such old machine (luatex 
benefits from large cpu caches), do you get a reasonable page per second 
rate?

the bad is that viewers clip lines so additional shift action is needed

unless one forces page destinations for all (which is an option)
