cketti 8e627834c1 Changed font size unit from DIP to SP
"Scale-independent Pixels - this is like the dp unit, but it is also
scaled by the user's font size preference. It is recommend you use this
unit when specifying font sizes, so they will be adjusted for both the
screen density and the user's preference." - Android Developer Docs
