Timeline: nail the problem with calculating overall vertical space

In the end, I used the profile building pass to also calculate and sum up the vertical offsets.
Seems to be the only sane approach to get really precise values, since adjacent
upwards slopes can be combined at various places (and I do not want to use the
actual drawing code for this calculation)
