Dear LilyPonders,
I can get the extents of a grob with `ly:grob-extent`. What is the corresponding Scheme function to set the extents? Or to ask in a different way: At the time when properties are processed and you have to manipulate stencils, changing the stencil of a grob doesn't change the extents of this grob, AFAICS. How can I adjust the extents at this stage to fit the dimensions of the stencil (even if LilyPond no longer needs and/or uses the values for positioning)? Werner
