draft text- CGM gzip compression

[Don Larson <dlarson@cgmlarson.com>]

All

Insert under 1.2 Normative references:

   RFC 1952
     GZIP file format specification

Insert new section under 2.4 Encoding:

2.4.1 Compression

HTTP/1.1 allows for compressed data to be passed from server 
to client,
which can result in significant file size reduction.  CGM 
data maybe 
compressed for transmission using gzip compression. It is 
recommended 
that gzip-compressed CGM files have the extension ".cgz" (all 
lowercase)
on all platforms.

Questions- 

Do we need to add CGZ under MIME type section of W3C Overview 
of WebCGM Profile?
