           Summary: Viewport lost "default" keyword, but is it still
                    needed?
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: PC
        OS/Version: Mac OS X 10.5
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebCore Misc.
        AssignedTo: webkit-unassigned at lists.webkit.org

In the past, a valid keyword for viewport value was "default". This would
become the webkit client's default value for the given viewport key, similar
to "auto" when the value is undefined.

I don't think this concept is mentioned in the "css-viewport" spec, but this is a
regression from former behavior and functionality:
http://people.opera.com/rune/TR/css-viewport/

I'm still trying to work out whether or not it needs a new "ValueDefault"
enum value, or if "default" is just a way to explicitly say "ValueAuto".
Also, is this even necessary anymore? It seems as if web content
wants to dynamically change its viewport, it should just set the <meta>
tag again, and that will entirely replace the old viewport settings.
