The trouble with tweaking the ViewBox was that the amount of the
adjustment is expressed in the coordinate system of the image, not the
coordinate system of the bitmap that is being rendered. That means that
the additional space doesn’t necessarily extend to the single physical
pixel needed to resolve the issue.
Also adds flag icon for each language.
One limitation is that the language button doesn’t work properly when
accessed via the “more” menu of the page controls.
@BramChen - could you help me choose the most appropriate flags to use
for the variants of Chinese?
