[CSSWG][css-grid-3] First Public Working Draft of CSS Grid Layout Level 3

The CSS WG has published a First Public Working Draft of the CSS Grid Layout 
Module Level 3 aka CSS Masonry Layout:

     https://www.w3.org/TR/css-grid-3/

This First Public Working Draft represents masonry layout in two syntactic 
forms: a grid-integrated syntax, and a grid-independent syntax, both of which 
are outlined as alternatives. We hope publication of this draft facilitates 
discussion about their relative merits.

The CSSWG has resolved to adopt fully mixed track sizing for this layout 
model, allowing all the possible track listings expressible in CSS Grid Layout 
for masonry layout as well. This unifies the two incoming proposals' 
underlying layout models; and therefore both syntactic forms represent 
essentially equal capabilities for masonry layout (though there are some open 
issues about possible differences in their initial values).

To address performance concerns with mixed track sizing, the draft outlines 
performance optimizations in the layout model and adopts some simplifying 
heuristics for e.g. subgrids.

We are grateful to the designers and developers who commented in the issues 
with their use cases, diagrams, and demos, which informed the development of 
this module.

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

We expect development of this module to proceed rapidly from this point 
forward, since it builds on the existing foundation of the grid layout algorithms.

For the CSS WG,
