The Symbol Editor provides a set of general graphical shapes
that can be used as symbol elements. All symbol elements except bitmaps are
vector-based and therefore they can be used with precision and are easy to
scale. In this chapter we introduce each shape and provide detailed descriptions
of how to create it and how to change such shape specific properties as
location, size, colors and line style. Those editing operations that are common
for all shapes, like scaling and aligning, are discussed in Section
3.3.
