27  * Facade to the PrintWriter returned by Response.
28  * This will grow to include more support for JSPs ( and other templating
29  * systems ) buffering requirements, provide support for accounting
30  * and will allow more control over char-to-byte conversion ( if it proves
31  * that we spend too much time in that area ).
32  *
33  * This will also help us control the multi-buffering ( since all writers have
34  * 8k or more of un-recyclable buffers).
