Initial draft for addressing CJK layoug grid DRs

[MURATA Makoto]

Folks,

Here is a very early draft.

Regards,
Makoto

1) Additions to 17.6.3  (Single Column Definition )

When vertical writing is chosen by the value of the val attribute of
the textDirection element (17.6.20) for the current section, columns
are arranged from top to bottom and the column spacing is vertical.

2) Additions to 17.6.4 (Column Definitions)

If a w:cols element is not present, <w:cols w:equalWidth="1" w:num="1"/> 
is assumed.  (Note: Is this true?)

If a w:cols element does not have the equalWidth attribute, it is 
assumed to have w:equalWidth="1" (Drafting note: Is this true?)

When vertical writing is chosen by the value of the val attribute of
the textDirection element (17.6.20) for the current section, columns
are arranged from top to bottom and the column spacing is vertical.

3) Additions to 17.18.14 ST_DocGrid (Document Grid Types)

Drafting note: Clarify the differences between "linesAndChar" and
"snapToGrid".  In particular, make clear that "linesAndChar" does not
indicate aligment to the character grid.


4) Modifications to 17.3.2.34 snapToGrid (Use Document Grid Settings
For Inter-Character Spacing)

Additional charater spacing is ALWAYS added.

Aligment to the character grid is guranteed only when the val attribute 
of this element is "true" or "1".


5) New sublclauses or annex

X.1 Paper size, page margins, and columns

Drafting note: Introduce the first five diagrams and add explain them
in prose.  Reference 17.6.13 (Page size) and 17.6.11 (Page margins)

X.2 Establishing the Document Grid 

Drafting note: Introduce the next four diagrams and explain them in
prose.  Reference 17.6.5 (Document Grid) and 17.18.14 ST_DocGrid
(Document Grid Types).
