* hildon-widgets/hildon-font-selection-dialog.c: Adding a
	"font-scaling" property that allows to customize the output of the
	Preview dialog during font selection. By default font-scaling equals
	1.0 = no change. Applications/clients should apply here the
	font-scaling they use for user-output/visualization. Fixes #NB19001.
