well, we have already

state=repeat: same background each upcoming page
state=start : enable background (calculate each time)
state=stop  : disable backgrond

so we would have

state=once  : enable background and after this page disable it

in this case 'once' is kind of "start" before and "stop" after \page

a range makes not much sense as one seldom knows the page in advance so 
that would then be named pages; however, as we have 25 page areas it 
would involve more testing then i currently want to do (the otr is 
already not that fast)
