Hmm. This means that

becomes essentially

right? If you say `expanded by x' do you mean x/2 on each side?
The diagram is right, but by 'expanded by x' I mean x on each side. That is, the total horizontal expansion is 4x, half of which is sloped.

Example, please.
This was more of an internal-code comment than something that you can directly do in a .ly file. One application, though, is that you can decide that TextScripts should have a horizontal-padding of 2 while VoltaBrackets should have a horizontal-padding of 0. Previously, the same max-slope applied to every object in the skyline. This functionality is not yet exposed to the user but it will be soon (hopefully today). The property to look for will be called outside-staff-horizontal-padding.
