mouse-over highlighting, and selection
highlighting, 'DynamicImage', which produces JPEG
or PNG images on the server with an AWT-like
painting listener method and sophisticated caching
options, 'AjaxTextField', an AJAX powered text

alpha-transparent .png images display correctly on
all browsers incuding Internet Explorer 5.
