Hi webkit-dev, 

Mihnea and myself have been working on an early WebKit prototype of CSS
Regions and CSS Exclusions proposals. These proposals are being discussed
with the W3C CSS WG (see reference below). CSS Regions and CSS exclusions
allow more sophisticated, magazine-layouts, to be built using HTML and

We are looking forward to integrate our work into WebKit. We have added
bug # 57309 to track the patches. The changes will be guarded by
ENABLE(REGIONS) and ENABLE(EXCLUSIONS) and will be disabled by default.

We'll be setting up a buildbot to track the ENABLE(REGIONS) and
ENABLE(EXCLUSIONS) build shortly. We expect this feature to be eventually
enabled by all ports.  Looking forward to your comments.
