\HTMLPurifier_Filter
Represents a pre or post processing filter on HTML Purifier's output
Sometimes, a little ad-hoc fixing of HTML has to be done before
it gets sent through HTML Purifier: you can use filters to acheive
this effect. For instance, YouTube videos can be preserved using
this manner. You could have used a decorator for this task, but
PHP's support for them is not terribly robust, so we're going
to just loop through the filters.
Filters should be exited first in, last out. If there are three filters,
named 1, 2 and 3, the order of execution should go 1->preFilter,
2->preFilter, 3->preFilter, purify, 3->postFilter, 2->postFilter,
1->postFilter.
