 // FrameHost is the set of global data shared between multiple frames
 // and is provided by the embedder to each frame when created.
 // FrameHost currently corresponds to the Page object in core/page
 // however the concept of a Page is moving up out of Blink.
 // In an out-of-process iframe world, a single Page may have
 // multiple frames in different process, thus Page becomes a
 // browser-level concept and Blink core/ only knows about its LocalFrame (and
 // FrameHost).  Separating Page from the rest of core/ through this indirection
 // allows us to slowly refactor Page without breaking the rest of core.

   // Corresponds to pixel density of the device where this Page is

   // This value does not account for Page zoom, use LocalFrame::devicePixelRatio
   // instead.  This is to be deprecated. Use this with caution.
   // 1) If you need to scale the content per device scale factor, this is still
   //    valid.  In use-zoom-for-dsf mode, this is always 1, and will be remove
   //    when transition is complete.
   // 2) If you want to compute the device related measure (such as device pixel
   //    height, or the scale factor for drag image), use
   //    ChromeClient::screenInfo() instead.
