Some breakage in GeoDataTrack as discussed:


src/lib/geodata/data/GeoDataSimpleArrayData.h
<http://git.reviewboard.kde.org/r/103191/#comment7384>

    Why would GeoDatasimpleArrayData be a geometry type? Is it a rendering object like the polyline of a placemark?
    I don't find the kml spec matching this object concept, it seems more related to SimpleData, which is rather abstract data type, so neither a feature nor a geometry.



src/lib/geodata/data/GeoDataTrack.cpp
<http://git.reviewboard.kde.org/r/103191/#comment7385>

    This code basically builds a full map of all valid m_when elements just to extract an upperBound and check one point after it... Could it not consist in a QList world of finding the 2 valid times around when and keep the extrapolating code?



src/lib/geodata/data/GeoDataTrack.cpp
<http://git.reviewboard.kde.org/r/103191/#comment7387>

    This implementation does not keep date sorted track, so breaks the display of for instance satellite.



src/lib/geodata/data/GeoDataTrack.cpp
<http://git.reviewboard.kde.org/r/103191/#comment7386>

    This new implementation will have the effect of removing points without time iiuc. 
    Previous code had a while( d->m_when.at(i) < when) instead which sounds better.
