Now, concerning backgrounds: i need to fix that for the first case (use \openlineheight instead of lineheight in calculations) [you may enter an bug entry in the collector]

Hans, Would it be possible to add the 'framed' functionality of \startbackground to \definetextbackground? Should be doable using some extra metafont macros, right? Then \startbackground could be flagged as obsolete. ;-) Taco
