794  Some of the techniques have been used in technical drawing,  together create the non-disruptively linking
795  we have added the continuous animation. XXX  BuoyOING hypertext user interface.
796    The techniques are made possible by modern
797    graphics accelerators with texture mapping

800    Our prototype demonstrates the techniques
801    on a simple structure consisting of 2D canvases
802    and xanalogical data.
803    The canvas can easily be extended to support
