Bug 795657: Integrate native viewport configuration better into async pan-zoom code. r=jwir3,roc a=blocking-basecamp This is a rollup of the following patches - Change the interpretation of FrameMetrics.mZoom to a "resolution-indepedent zoom", instead of a resolution-depedent scale factor. r=roc - Remove mention of "meta" from TabChild. r=roc - Remove some useless logging. r=roc - Tag FrameMetrics with its composition bounds at paint time. r=roc - Add a helper to calculate the render resolution for a FrameMetrics. r=roc - Add a helper to compute the approximate CSS dimensions a FrameMetrics will cover during composition. r=roc - BrowserElementScrolling doesn't actually care about zoom or resolution. r=roc - Accept the viewport that content has calculated, when it's received the latest widget geometry update. r=roc - Mechanically separate uses of zoom/resolution based on new definitions. r=roc - Convert GetViewportInfo()'s resolution-dependent scale into resolution-indepedent zoom. r=roc - Reinterpret defaultZoom == 0.0 as "intrinsic scale". r=jwir3,roc

interface nsIDOMWindow;

 * nsIBrowserGlue is a dirty and rather fluid interface to host shared utility 
 * methods used by browser UI code, but which are not local to a browser window.
 * The component implementing this interface is meant to be a singleton
 * (service) and should progressively replace some of the shared "glue" code 
 * scattered in browser/base/content (e.g. bits of utilOverlay.js, 
 * contentAreaUtils.js, globalOverlay.js, browser.js), avoiding dynamic 
 * inclusion and initialization of a ton of JS code for *each* window.
 * Dued to its nature and origin, this interface won't probably be the most
 * elegant or stable in the mozilla codebase, but its aim is rather pragmatic:
 * 1) reducing the performance overhead which affects browser window load;
 * 2) allow global hooks (e.g. startup and shutdown observers) which survive
 * browser windows to accomplish browser-related activities, such as shutdown
 * sanitization (see bug #284086)
