Jan Henning 320ff25d1c Bug 1328868 - Part 1 - Allow setting a global zoom factor via nsLayoutUtils. r=tnikkel
For Android we want to be able to set a global zoom factor that will scale any page where font inflation is not turned on.

Android makes the system font scale available as a float factor. For our purposes, converting this to a percentage based value and rounding to an integer is accurate enough and enables us to pass this value as a standard Gecko int preference. This means we can make use of the standard infrastructure for setting and retrieving Gecko-side preferences both from Java and JS (the latter during testing), as opposed to having to write custom JNI and C++/IDL helper functions.

To that effect, we implement a method for retrieving that setting via nsLayoutUtils, analogous to the current font inflation settings. Since we later want to clamp the effective text zoom resulting from that setting by zoom.minPercent and maxPercent, we add var caches for them in nsLayoutUtils as well.
