1.) Index array of the TinMesh has been divided in multiple smaller arrays (so that each array contains at most 65535 indices) in order to prevent rendering errors.
2.) TinMesh::ComputeAltitudeAt() has been implemented. Result is approximated using the elevation of the closest sample (measured by Euclidean distance).
3.) TinData::LowestPoint(), TinData::HighestPoint() and TinData::StretchValues() have been implemented.
