/**
 *  @desc A plane-shaped 3D object containing a bitmap image.
 *
 * Use ````ImagePlane```` to embed bitmap images in your scenes.
 *
 * As shown in the examples below, ````ImagePlane```` is useful for creating ground planes from satellite maps and embedding 2D plan
 * view images in cross-section slicing planes.
 *
 * # Example 1: Create a ground plane from a satellite image
 *
 * In our first example, we'll load the Schependomlaan model, then use
 * an ````ImagePlane```` to create a ground plane, which will contain
 * a satellite image sourced from Google Maps.

 *
 * # Example 2: Embed an image in a cross-section plane
 *
 * In our second example, we'll load the Schependomlaan model again, then slice it in half with
 * a {@link SectionPlanesPlugin}, then use an ````ImagePlane```` to embed a 2D plan view image in the slicing plane.
