[css3-Grid] New Editor's Draft published

There is a new editor's draft of the CSS3 Grid Layout module available: http://dev.w3.org/csswg/css3-grid-align/

Significant updates include:

*	Removing the grid-layer property in favor of using z-index
*	Multiple updates to grid-sizing algorithm, including an update for shrink-to-fit Grid Elements

Further discussion of the z-index and algorithmic update changes is available at the CSS Grid Layout wiki: http://wiki.csswg.org/spec/css3-grid-layout

We also have a complete list of changes made since the last Editor's Draft:

o	Section 2.4, Section 9: Removed the grid-layer property in favor of using z-index.
o	Section 6.5: Clarified whitespace rules.
o	Section 6.5: Changed "positive-number" to "positive-integer".
o	Section 6.5: Updated the spec to clarify that percentages-sized grid tracks are undefined when inside content-sized grids.
o	Section 8.1: Updated the spec to show that percentage-sized grid items resolve themselves against the grid cell, rather than the grid element.
o	Section 10.1: Updated definition of RemainingSpace for shrink-to-fit situations.
o	Section 10.2: Renamed NormalizedFractionBreadth variable to NormalizedFractionValue in the CalculateNormalizedFractionBreadth algorithm
o	Section 10.2: Addressed typos (e.g. Space -> SpaceToFill) in CalculateNormalizedFractionBreadth
o	Section 10.2: Updated CalculateNormalizedFractionBreadth to remove an unneeded inner loop in step 7.
o	Section 10.2: Updated steps 2 and 3 in DistributeSpaceToTracks function to correct use of delta variable
o	Section 10.2: Updated step 6 in ComputeUsedBreadthOfGridTracks to cover shrink-to-fit Grid Elements

We look forward to comments and feedback, and would be happy to discuss these changes further during a future telcon.

Thanks,
