Hi, I tried to help in the thread "TabStaff arpeggio problem when first thing on line" but I realized that I do not understand X- and Y-extends.
Is there more to find than this http://lilypond.org/doc/v2.18/Documentation/notation/aligning-objects and http://lilypond.1069038.n5.nabble.com/accidental-spacing-multiple-signs-X-extent-and-ly-accidental-interface-width-td50448.html ? How are numbers of the "wrong" sign treated? X-extent = #'(2 . -2) % instead of (-2 . 2) for instance Is the object width then -4 staff spaces or 0 or sth. else? I see some unpredictable behaviour. For instance, (0 . -0.0001) is different from (0 . 0) but not from (0 . -10). (0 . 0) leaves some space for the object, the negative values seem to collapse it completely. How does that happen? Are these distances like rectangles around the reference point? And no such rectangles may overlap? Is there a way to print them (like "show control points" in Frescobaldi or "annotate-spacing" in the paper block)?
