12.3 Lidskjalv Graphics and FigureItems

The Lidskjalv fragment groups graphics and figureitems contain a simple set of graphics routines to allow for some graphics in Lidskjalv. Both fragments are based on the notation of a Pen, and whereas graphics defines a procedural graphics library with 'draw' and 'fill' operation (but with no automatic refresh-handling like immediate drawings in the Bifrost Canvas), the figureitems resemble Bifrost predefined graphical objects somewhat. They can be thought of as a simplified 'light-weight' graphical library to use as an alternative to Bifrost in Lidskjalv.

Notice, however, that the figureitems in Lidskjalv are present mostly for historical reasons, and that it is being discussed to replace them with the Bifrost equivalents.
