[CSSWG][css-inline-3] Updated WD of CSS Inline Layout L3

The CSS WG has published an updated Working Draft of the CSS Inline Layout 
Module Level 3:


This module describes the alignment and sizing of inline-level boxes and text.
It also introduces a special layout mode for drop caps and similar initial 
letter styling.

This is a significant update which pulls in some major new features, including 
control over whether to use a box’s first/last line’s baseline for baseline 
alignment ('baseline-source') and new proposals for altering how line heights 
are calculated and for controlling leading ('line-sizing' and 'leading-trim', 
currently). Note that these proposals are in early drafting stages and are 
expected to change significantly.

The draft now also includes a high-level description of the inline layout box 
and imports prose from CSS2 detailing how line heights are calculated:

Significant changes are all listed at:

(Note that the initial letter layout section has been reorganized and tweaked 
substantially for readability, so expect messy diffs in this section against 
the previous publication. But few substantive changes. I'm saving the 
significant substantive changes for the next publication so this one can be 
used as a diff base. ;)

Plans for the next update include working on major design questions on 
'line-sizing' and 'leading-trim', filling out details on how vertical-align 
and related features actually work (copying out from CSS2), and describing 
more rigorously the initial letter layout model.

Please send any comments to the mailing list <www-style@w3.org>, prefixed with 
[css-inline-3] (as I did on this message) or (preferably) file them in the 
GitHub repository at https://github.com/w3c/csswg-drafts/issues

For the CSS WG,
