The legend plane, bike, foot should only be displayed if appliccable
In 'all sections synchronized' mode and especially since issue #10 (closed) is solved the legend with all sorts of transportation should not be shown anymore. The question is, whether a legend based on the already preseent info in edit section of gpxmotion should be generated by gpxmotion or whether an entry to the edit section could be added, in which the user could simply optionally define a picture with the legend instead. I would prefer the 2nd option because it is much more flexible and less debatable. A second such optional entry could be used for the watermark.
