A vertex format defines what attributes make up a vertex.  A VertexFormat can be provided
to a {@link Geometry} to request that certain properties be computed, e.g., just position,
position and normal, etc.

@param {object} [options] An object with boolean properties corresponding to VertexFormat properties as shown in the code example.

@alias VertexFormat
@constructor

@example
// Create a vertex format with position and 2D texture coordinate attributes.
const format = new Cesium.VertexFormat({
  position : true,
  st : true
});
