This implements computation of the font size inflation factor for a given frame. Since Fennec does layout using a fake viewport whose width represents a typical viewport width on the desktop and then allows users to pan and zoom, fonts are not always readable even when zoomed. The goal of this font size inflation is to ensure that when a block of text is zoomed to fill the width of the device, the fonts are large enough to read. We do this by increasing the font sizes in the page. Since this increase is a function of the width of the text's container, the inflation must be performed (in later patches in this series) after style data computation and after intrinsic width computation. The font size inflation factor does not vary *within* a block. Since sync uses a whitelist (the services.sync.prefs.sync.* prefs) for preferences (i.e., preferences are not synced by default), this patch does not make any changes relating to sync, since we do not want the inflation preferences synced across devices (since preferred settings are likely to be device-specific).
