Re: Give slurs skylines in outside-staff-priority calculations. (issue 5504055)

[Janek Warchoł]

Hi Mike,

(i've come back finally) When i was thinking about LilyPond lately, i
decided that changing character outlines from boxes to something more
precise was perhaps the most important thing we should improve now -
and i see that you are working on this! Great!
My (quick) question is: would be easy to apply your solution to other
objects?  I know that lyrics and dynamics really need improvement in
this area too - see this example: http://www.sendspace.com/file/dm4ua2
(source is attached to pdf).

Many thanks!
Janek
