Review comment (bug):
`collision_segments` seem to be set wrong unless I'm missing something. It could probably just use the raycast line like before, or the debug shape vertices.

Code after:
	const Color gizmo_color = EDITOR_DEF("editors/3d_gizmos/gizmo_colors/shape", Color(0.5, 0.7, 1));
	create_material("shape_material", gizmo_color);
	const float gizmo_value = gizmo_color.get_v();
	const Color gizmo_color_disabled = Color(gizmo_value, gizmo_value, gizmo_value, 0.65);
	create_material("shape_material_disabled", gizmo_color_disabled);
}
