Description Rik Cabanier 2012-07-20 15:44:22 PDT 
I would like to add CSS blending to WebKit.
We have a draft specification that we will push to WD soon.

The first implementation will be done using the 'webkit-' prefix and implement a subset of the whole feature (only the blending of whole elements).

How will this work with compositing?

> How will this work with compositing?

I was planning on adding compositing at a later stage. For now, blending will always be done with 'src-over'.

You should add CSS_COMPOSITING to all the build system first. See http://trac.webkit.org/changeset/123350 for an example.

You should also be adding CSS parsing tests at this stage.
