KSES is too slow to use for realtime output.

It’s used by WP/bbPress *before* the post is saved permanently (pre_post filter)

But bbcode is stored as bbcode, not converted HTML.

So it has to be converted to html each time a post is shown (post_text filter).

So KSES is too slow for that.

(plus I don’t want to use an external function with regex matches, which makes it ten times more complex)
