This patch is potentially interesting on the Freerunner due to the 3x
higher dpi of the screen. The patch makes future extensions for layers,
non-merkatoor and no wgs84 more error prone and therefore currently is
not suitable for tangoGPS. However, you can ask the packagers of SHR
etc. if they are interested in inclusion.
