4.5.4 Adjusting horizontal spacing for specific layout objects

In addition to the general-purpose parameters of the default spacing algorithm that apply to all elements of the score or spacing section, several properties serve to operate adjustments on a per-object-type-basis. Examples include adjusting the distance from clefs to time signatures, but not from clefs to notes when there is no time signature, or stretching notes further apart in the presence of a printed text so that it does not overlap with the next note. Tweaking these first requires identifying the type of spacing at play.
