Normally, xteddy just sits around doing nothing. After
all, that's what teddy bears are for. Look at him, talk to
him, place heavy windows on top of him, zap him around
until he becomes dizzy, do what you like; he will always
be your true (albeit virtual) friend.
Unlike the original version by Stefan Gustavson, this
version can display other image formats, and comes with a
number of other images - see xteddy_test.
