// This file contains the functions used to create the context menu for the browser's

// main content web view.

 // Context menu spec:

 // ------------------

 //Images---Options to be shown under an "Links/Pictures" tab

 // Save

 // Share

 //

 //Images that are also links---Options to be shown under an "Links/Pictures" tab

 // Open link in new window

 // Save

 // Share

 //

 //URLs-- Options to be shown under a "Links/Picture" tab

 // Open link in new window

 // Share

 //

 // Note: the options offered for a link or a picture or a combo

 // link/picture are slightly different, but the right set should

 // always be shown under a single tab contextual to what's been

 // pressed.

 //

 // If no link or picture has been long-pressed and the user is in

 // the CMB - say to see page options or the view switcher--the user

 // can still press on the Links/Pictures tab. Because there is no

 // known context to present options, we instead show menu items for

 // the combined link/image object as grayed out with text on top

 // approximating this: "Long-press on a web link or picture to use

 // these actions."
