[GTK] Add CSS Grid Layout as experimental feature

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Manuel Rego Casasnovas]

Now that we've a runtime feature for CSS Grid Layout again (bug #157134),
we can recover the old patch to enable it from an env variable (bug #127089).

I usually prefer to leave one blank line above variable declarations, especially when they're not initialized. It's easier to read IMO.

The compile flag is still off by default. I don't think the runtime flag serves any useful purpose if this functionality is compiled out by default. Presumably, you would only change the build flags if you really want to test CSS grid layout, so it's currently just another obstacle to overcome.

I think we should flip ENABLE_CSS_GRID_LAYOUT to be on by default.

Yeah I agree, at least for WebKitGTK+ we want to build it by default (and keep the runtime flag disabled by default).

Should we modify Source/cmake/WebKitFeatures.cmake to make it ON by default?
Or the change should go somewhere else?

Yes.

Also in FeatureList.pm if it's not already.
