/**
* Configures the appearance of {@link Entity}s when they are xrayed, highlighted or selected.
*
* * XRay an {@link Entity} by setting {@link Entity#xrayed} ````true````.
* * Highlight an {@link Entity} by setting {@link Entity#highlighted} ````true````.
* * Select an {@link Entity} by setting {@link Entity#selected} ````true````.
* * When {@link Entity}s are within the subtree of a root {@link Entity}, then setting {@link Entity#xrayed}, {@link Entity#highlighted} or {@link Entity#selected}
* on the root will collectively set those properties on all sub-{@link Entity}s.
* * EmphasisMaterial provides several presets. Select a preset by setting {@link EmphasisMaterial#preset} to the ID of a preset in {@link EmphasisMaterial#presets}.
* * By default, a {@link Mesh} uses the default EmphasisMaterials in {@link Scene#xrayMaterial}, {@link Scene#highlightMaterial} and {@link Scene#selectedMaterial}
* but you can assign each {@link Mesh#xrayMaterial}, {@link Mesh#highlightMaterial} or {@link Mesh#selectedMaterial} to a custom EmphasisMaterial, if required.
*
* ## Usage
*
* In the example below, we'll create a {@link Mesh} with its own XRayMaterial and set {@link Mesh#xrayed} ````true```` to xray it.
*
* Recall that {@link Mesh} is a concrete subtype of the abstract {@link Entity} base class.
*
* ````javascript
* new Mesh(viewer.scene, {
* geometry: new BoxGeometry(viewer.scene, {
* edgeThreshold: 1
* }),
* material: new PhongMaterial(viewer.scene, {
* diffuse: [0.2, 0.2, 1.0]
* }),
* xrayMaterial: new EmphasisMaterial(viewer.scene, {
* fill: true,
* fillColor: [0, 0, 0],
* fillAlpha: 0.7,
* edges: true,
* edgeColor: [0.2, 1.0, 0.2],
* edgeAlpha: 1.0,
* edgeWidth: 2
* }),
* xrayed: true
* });
* ````
*
* Note the ````edgeThreshold```` configuration for the {@link ReadableGeometry} on our {@link Mesh}. EmphasisMaterial configures
* a wireframe representation of the {@link ReadableGeometry} for the selected emphasis mode, which will have inner edges (those edges between
* adjacent co-planar triangles) removed for visual clarity. The ````edgeThreshold```` indicates that, for
* this particular {@link ReadableGeometry}, an inner edge is one where the angle between the surface normals of adjacent triangles
* is not greater than ````5```` degrees. That's set to ````2```` by default, but we can override it to tweak the effect
* as needed for particular Geometries.
*
* Here's the example again, this time implicitly defaulting to the {@link Scene#edgeMaterial}. We'll also modify that EdgeMaterial
* to customize the effect.
*
* ````javascript
* new Mesh({
* geometry: new TeapotGeometry(viewer.scene, {
* edgeThreshold: 5
* }),
* material: new PhongMaterial(viewer.scene, {
* diffuse: [0.2, 0.2, 1.0]
* }),
* xrayed: true
* });
*
* var xrayMaterial = viewer.scene.xrayMaterial;
*
* xrayMaterial.fillColor = [0.2, 1.0, 0.2];
* xrayMaterial.fillAlpha = 1.0;
* ````
*
* ## Presets
*
* Let's switch the {@link Scene#xrayMaterial} to one of the presets in {@link EmphasisMaterial#presets}:
*
* ````javascript
* viewer.xrayMaterial.preset = EmphasisMaterial.presets["sepia"];
* ````
*
* We can also create an EmphasisMaterial from a preset, while overriding properties of the preset as required:
*
* ````javascript
* var myEmphasisMaterial = new EMphasisMaterial(viewer.scene, {
* preset: "sepia",
* fillColor = [1.0, 0.5, 0.5]
* });
* ````
