This is a stub/very preliminary implementation of calling JSXGraph for
3D Joyce applets. The only element/construction method implemented so far
is a free point.
NOTE: This implementation is so far extremely buggy. Loading a page with a
3D applet such as
http://aleph0.clarku.edu/~djoyce/java/elements/bookXI/defXI9.html
appears to enter a loop in which the div containing the JSXGraph Board
progressively grows larger and larger, while using a tremendous amount
of cpu.
Turns on 3D viewing only for the constructions that use a 3D primitive, but loads the more extensive web3d bundle from the embedded GeoGebra package whenever any applet on the page uses 3d. (The idea is to only require the loading of one bundle per page.) Provides progress on #36.
