/**
* The ScaleGizmo provides interactive 3D manipulation handles for scaling/resizing
* {@link Entity}s in a {@link Scene}. It creates a visual widget with box-tipped lines along the
* X, Y and Z axes, planes at their intersections, and a center box, allowing precise control over
* object scaling through direct manipulation. The gizmo's visual appearance can be customized
* away from the defaults as required.
*
* Note that the gizmo can be driven by both mouse+keyboard and touch input.
*
* ```javascript
* // Create a layer for rendering all gizmos
* const gizmoLayer = pc.Gizmo.createLayer(app);
*
* // Create a scale gizmo
* const gizmo = new pc.ScaleGizmo(cameraComponent, gizmoLayer);
*
* // Create an entity to attach the gizmo to
* const entity = new pc.Entity();
* entity.addComponent('render', {
* type: 'box'
* });
* app.root.addChild(entity);
*
* // Attach the gizmo to the entity
* gizmo.attach([entity]);
* ```
*

*
* - [Scale Gizmo](https://playcanvas.github.io/#/gizmos/transform-scale)
* - [Editor](https://playcanvas.github.io/#/misc/editor)
