In an ePiX file, points are denoted with LATEX glyphs (``markers'') or text boxes (``labels''). A marker occupies a box of zero size, and is placed at a specified Cartesian location. A label has typographical size, so its placement is more involved. When the size or aspect ratio of a figure is adjusted, the font size stays the same. In order to keep a label aligned properly over a range of sizes, a scale-invariant alignment point is attached to each label, and Cartesian coordinates are used to position the alignment point. The alignment point is controlled both by a true-pt offset and an optional LATEX-style alignment option.
