Description
    Writes point data in glTF v2 format

    Two files are generated:
    - filename.bin  : a binary file containing all scene entities
    - filename.gltf : a JSON file that ties fields to the binary data

    The output can contain both geometry and fields, with additional support
    for colours using a user-supplied colour map, and animation of particle
    tracks.

    Controls are provided via the optional formatOptions dictionary.

    For non-particle track data:

    \verbatim
    formatOptions
    {
        // Apply colours flag (yes | no ) [optional]
        colours     yes;

        // List of options per field
        fieldInfo
        {
            p
            {
                // Colour map [optional]
                colourMap       <colourMap>;

                // Colour map minimum and maximum limits [optional]
                // Uses field min and max if not specified
                min             0;
                max             ...
