There are a few bugs. One well known in Opera 7.x is that the background
(image, color) is not clipped, only content.

clip is a property. The only shape supported is rect.
It has only one method "replace".
?

Opera 7.20 beta now supports getComputedStyle and getComputedValue.
Your getClip function is not best I think. I would have been using
currentStyle for IE instead of style... if you want to get the default
css declarations of existing elements.

Invalid CSS code.
"a unit must be specified for length values"
http://www.w3.org/TR/CSS2/syndata.html#parsing-errors
" The format of a length value (denoted by <length> in this
specification) is an optional sign character ('+' or '-', with '+' being
the default) immediately followed by a <number> (with or without a
decimal point) immediately followed by a unit identifier (e.g., px, deg,
etc.)."
http://www.w3.org/TR/CSS2/syndata.html#value-def-length
Your getClip function should be coded in a way that it should return
rect(auto auto auto auto)
or
rect(auto,auto,auto,auto)
in any DOM2 and CSS2 compliant browser.

It's always better to quote attribute values as it speeds up a bit
parsing and rendering and it avoids errors of all kinds in all sorts of
situations.
