one has to render a document (page stream) in order to wee what end up 
where .. a viewer has that info so it can decide to act upon it (apart 
from some gambling with words clipped in the middle of a character)

this is not something for context to provide (it would mean keeping 
track of what gets clipped, and then compensating for it because it can 
still contribute to placement of following stuff, and then how about 
half clipped stuff)

if i had a lifespan of 1000 years or were on a boring trip to another 
planet it might make a nice (although pointless) challenge to keep me 
occupied
