           Summary: [Chromium] Plumb DPI info into PlatformScreen
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Unspecified
        OS/Version: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit API
        AssignedTo: webkit-unassigned at lists.webkit.org
        ReportedBy: fsamuel at chromium.org

In order to properly implement the Viewport Meta tag, we need to make a full size web page's CSS pixel be equal to a reference pixel in size. To do the proper scaling calculations, we need access to the screen dpi in WebKit.

So plumb the DPI info through the following:

PlatformScreen.h
PlatformScreenChromium.cpp
PlatformSupport
WebWidgetClient
WebScreenInfo
WebScreenInfoFactory (x11) where we have a X Display to inquire things from.
