Here is a loose end that has been kicking around for two years (since 
Houston) -- deprecated compression types in BITONAL TILE and TILE.  If you 
look at the current editors draft, you'll see:

>T.19.28  BITONAL TILE
>----------
>List allowable compression types: 0, 1, 2, 5, or 6.
>Requirements on row padding: None.
>Other: The values 0, 1 are deprecated and may be removed from a future 
>version of WebCGM.

Green shading on 0, 1 in both places.  So apparently we intend to deprecate 
those two, null background and null foreground?  Deprecate means:  cannot 
appear in 2.0 content, but viewers must be prepared to handle (in 1.0 content).

Agreed, is that what we finally resolved here?

>T.19.29  TILE
>----------
>List allowable compression types: 0, 1, 2, 5, 6, 7, or 9
>Requirements on row padding: None.
>Other: The value 9 is the ISO registered value for compression method 0 of 
>PNG.
>The values 0, 1, 2 are deprecated and...

0,1 is green shaded in the first line, and 0,1,2 (2=Group3) is green shaded 
in the last.

So what is it that we finally resolved for TILE?

(Editorial comment -- IMO, these are all so trivial to implement that I 
have trouble recalling why we decided to deprecate in the first place.)
