/******************************************************************
 * FlashAgent.js: requires FlashApplet.js
 *
 * TG NOTES: I butchered this from the original AgentApplet,
 * deleting many methods that could not have worked due to
 * references to non-existing member variables, etc.  I
 * assumed that I was just getting rid of historical stuff
 * that was no longer supported anyway, but in the process,
 * it was evident that so much of it was broken anyway, that
 * now there is much less functionality.  Mainly, there is no
 * longer any code referring to movement and visibility, as
 * it is assumed that you must go thru this.dragBox for this
 * functionality.  Hopefully that functionality will get
 * re-added as needed, and in an manner which actually works.
