| Style sheet cache, to avoid repeated loading and parsing of the
stylesheet, and also to avoid introducing excessive memory overhead
such that multiple pages referring to the same stylesheet can use
the same instance. This is important since stylesheets can take up
a lot of memory when they are large. (The default stylesheet in Creator
took up about 5 megabytes for each usage, which quickly adds up when you
have many pages!)
