Silence OpenGL and OpenGL ES deprecation warnings in newer SDKs
Created attachment 335056 [details]
I'm seeing if this builds even with only a single one of the stanzas.
Looks like only using the stanza in Source/WebCore/config.h doesn't fix the build, and precompiled headers shouldn't be required to build, which means we need to add it in even more places (or put it in Source/WebCore/Configurations/WebCore.xcconfig)
Testing the WebCore.xcconfig solution on iOS now.
