As the comment says, find a better, publicly supported way of doing what this
code is doing.

GetComputedStyle is a supported method.  See
http://lxr.mozilla.org/seamonkey/source/content/xml/document/src/nsXMLContentSink.cpp#350
for an example.  I'm not sure if it will do completely what you want, but you
could hack the background-getting function to do what you want for
:-moz-viewport or :-moz-canvas or something fun like that (or provide a
different API).
