The CommentStripper class is a filter that removes all comments and processing instructions.
It also concatenates text nodes that are split by comments and PIs. This follows the rules for
processing stylesheets.

public void characters(CharSequence chars, int locationId, int properties)
Handle a text node. Because we're often handling stylesheets on this path, whitespace text
nodes will often be stripped but we can't strip them immediately because of the case
[element] [!-- comment --]text[/element], where the space before the comment is considered
significant. But it's worth going to some effort to avoid uncompressing the whitespace in the
more common case, so that it can easily be detected and stripped downstream.
