Chris Lord 8947fea4fd Bug 703141 - Refactor around the idea of a viewport and displayport. r=kats 
This patch refactors the code to make some of the value names and ownership
clearer, and to add the idea of a 'viewport' within a 'displayport'. The
displayport is the area of the page which is visible to the underlying buffer
and the viewport is the area of the page which is visible through the
application window.

--HG--
rename : mobile/android/base/ui/ViewportController.java => mobile/android/base/gfx/ViewportMetrics.java
