Compositing is behind a define that is currently turned off in WebKit builds.

Simon Fraser recommended that it should be turned on.

You need to do this in all the FeatureDefines.xcconfig files, and make sure ENABLE_CSS_COMPOSITING is included in the FEATURE_DEFINES lines.

A better comment would be "enable this feature on trunk." I don't think any further justification is required, but you might want to reference a bug or bugs about enabling it on other platforms.

Hello, can I go ahead and enable this on Windows too? Shouldn't cause any issues right?

No, feel free to do so.
Will all the CALayer and CG code work there too?

Should be fine yeah
Thanks

[Roger Fong]

Just kidding.
Simon says that the blend stuff uses CIFilters and on Windows there are no CIFilters.
So that won't work at all.
I think I'll just keep blending disabled and skip the tests on Windows.

[Dean Jackson]

We'll be able to do some of the operations on Windows using a back door. It will require code though.
