tilt, base_slope and azimuth are <rotate> elements recognized by collada.
Benefits:
- they are understood by a non-pv 3d software
- PV software can easily read the last number and based on the
sidindentify thattiltis21.8,azimuthis45andbase_slopeis10
Notes:
- the order is important
- the axis (first three numbers in the element), is constant
