The widget layout that was used resulted in a clipped usage bar. It also had a 6dip left offset inherited from the default layout which adds margin after the text (even if the text is empty here). Used a custom layout for the whole preference to fix this issue. Other fixes in the drawing code to prevent accumulative rounding issues. Change-Id: Ief9bf85260345355615c9670624d86f0893eb2d2
