//! Create a selectable trihedron
//! The trihedron includes 1 origin, 3 axes and 3 labels.
//! Default text of labels are "X", "Y", "Z".
//! Color of origin and any axis, color of arrows and labels may be changed.
//! Visual presentation might be shown in two, shaded and wireframe modes, wireframe by default).
//! There are 4 modes of selection:
//! - AIS_TrihedronSelectionMode_EntireObject to select trihedron,  priority = 1
//! - AIS_TrihedronSelectionMode_Origin       to select its origin, priority = 5
//! - AIS_TrihedronSelectionMode_Axes         to select its axis,   priority = 3
//! - AIS_TrihedronSelectionMode_MainPlanes   to select its planes, priority = 2
//!
//! Warning!
//! For the presentation of trihedron, the default unit of length is the millimetre,
//! and the default value for the representation of the axes is 100.
//! If you modify these dimensions, you must temporarily recover the Drawer.
//! From inside it, you take the aspect in which the values for length are stocked.
//! For trihedron, this is Prs3d_Drawer_LineAspect.
//! You change the values inside this Aspect and recalculate the presentation.
