Can we find a way to not have this in three different places!?

This is a strange use of USE(QTKIT). If it’s false, then you default to not using QTKit, but can turn it on at runtime. That’s not normally what our USE macros mean.

> +#else

>  #endif

Still need to wrap this in #if PLATFORM(COCOA)

I'd love to, but WebCore, WebKit, and WebKit2 each have their own definitions for their respective default settings.

I realize; this is just the first step. The next step is to actually disable the implementation. 

Meanwhile, having this USE macro means not having to repeat the same platform macro everywhere in each of the settings defaults.  I'm open to other ideas though.

Oh, good point.

Got rid of WTF_USE_WEBKIT and managed to have the WebKit and WebKit2 preference defaults derived from the WebCore ones.

As discussed in person, we probably need more tests updated, see <rdar://problem/20527672>.
