Fixed JS error when background-position has either "left" or "top" (fixes #14)
added unit tests
updated readme
most certainly a typo
added empty vbscript script element to work around IE hang
must remember to update readme concurrently
call handlePropertychange() in init() instead of duplicating code
added support for dynamically changing position and size of the background image (partial reimplementation of louisremi#8)
restore original position and z-index on detach
more minifiable
use the ms-approved markup
borrow init from PIE
open the door for ie6/7 (still untested);
i <3 spacer.gif
saved a few bytes
restore background-image on detach as well
more tests;
speed up tests with onreadystatechange
support dynamic background-image
