If you use the "text" parameter on Line() or Vector() and the text has contains more than one line, then the default behaviour is, that the first text line is anchored at the mounting drawn line itself and after line breaks the next text lines are drawn below the mounting drawn line. In some situations this may be undesired, e.g. if the mounting drawn line is a thick line than it can hide the second or third text line. You can change this behaviour by setting this global setting "shiftTextPosOnLines_toNonIntersecting" to "true". Then all text lines will be drawn above the line itself and the text block will end at the mounting drawn line.
