 ** Info
 **
 * Authored in NetBeans 3.2 IDE
 *
 * Grab images of current map, and robot. Scale to
 * dimensions of the applet panel. Get setup info
 * from position server CGI (goal points). Get
 * robot's position and orientation from the position
 * server and draw (client-pull). Scale all graphics based
 * on zoomlevel.
 *
 * Todo- Update frequency parameter loading, exception handling!,
 * server-side status reports, client-side controls?
 *
 *
 ** Revision History
 **
 * 0.61 3-15-2002
 * Fixed bug preventing screen redraws on image update.
 *
 * 0.60 1-13-2002
 * Much needed code cleanup of map rendering routines. Proper threading of 
 * image downloads.
 *
 * 0.52 11-2-2001
 * Minor UI tweaks. Still needs some work.
 *
 * 0.51 9-16-2001
 * Tracking-related bug seems to have dissapeared after adding some semaphores 
 * during screen redraws after changing zoom level. A minor bug during 
 * auto-tracking leaves remnants of the last screen around the borders of the 
 * animationPane after a zoom level change.
 *
 * 0.50 9-14-2001
 * Added work-arounds for buffer overflow when tracking and user attempts to
 * scroll (remove scroll bars when tracking, should fix this), and when
 * changing zoom level (tracking temporarily disabled during resize).
 * Still has a bug related to auto-tracking.
 *
 * 0.49 9-13-2001
 * Scrollbars now fully functional. Toolbar graphics enhancements.
 * Zoom level now fully functional. Added robot auto-tracking via Track button.
 *
 * 0.48 9-12-2001
 * Basic scrollbar functionality. Updated button logic on toolbar.
 * Basic zoom level support (needs work).
 *
 * 0.47 8-23-2001
 * Added toolbar with start/stop for position retrieval
 * and stubs for magnification level. Added stubs for scrollable window.
 *
 * 0.46 8-15-2001
 * Added basic goal point voting.
 *
 * 0.45 8-2-2001
 * Added basic target info window spawning.
 *
 * 0.44 7-31-2001
 * Added stub for goal point selection.
 *
 * 0.43 7-30-2001
 * Added basic goal plotting and labeling (currently disabled
 * for clarity). Fixed goal point parsing and array population.
 * Added getPos support.
 *
 * 0.42 7-28-2001
 * Fixed exception handling in NetIO routines. Extended parsing.
 * Fixed robotImage scaling.
 *
 * 0.41 7-27-2001
 * Added basic setup data retrieval and preliminary parsing.
 *
 * 0.4 7-25-2001
 * Added basic NetIO framework
 *
 * 0.3 7-23-2001
 * Basic image rendering using Java2D extensions for
 * image manipulation (rotation)
 *
 * Known Bugs- Java2D imagebuffer data not transparent when
 * pasted into 'g' canvas. Robot image has square borders
 * as a result
