    What do you think about making skylines consider the grob properties

    (1) keep everything as it is
    (2) skylines should reflect both grob rotation and grob extra-offset
    (3) skylines should reflect grob rotation only
    (4) skylines should reflect grob extra-offset only
    
    Obviously, (1) is sub-optimal and (2) and (4) would make extra-offset
    useless in many standard cases because it has been designed for arbitrary
    shifting around and shouldn't be hampered by skylines and it should be
    possible to make grobs overlap by using extra-offset.
    
    But skylines taking grob rotation into account would be a good idea,
    wouldn't it?
    
If it doesn't slow the code down too much, I would be in favor of having 
skylines reflect grob rotation.

I don't think we should have skylines reflect extra-offset.  Extra-offset is 
intended to apply after spacing decisions are made using skylines.  I believe 
we want to keep extra-offset, but continually reduce the need to apply it.

Thanks for looking at this!
