 * Uniforms of a program.
 * Those form a tree structure with a special top-level container for the root,
 * which you get by calling 'new WebGLUniforms( gl, program, renderer )'.
 *
 *
 * Properties of inner nodes including the top-level container:
 *
 * .seq - array of nested uniforms
 * .map - nested uniforms by name
 *
 *
 * Methods of all nodes except the top-level container:
 *
 * .setValue( gl, value, [renderer] )
 *
 * 		uploads a uniform value(s)
 *  	the 'renderer' parameter is needed for sampler uniforms
 *
 *
 * Static methods of the top-level container (renderer factorizations):
 *
 * .upload( gl, seq, values, renderer )
 *
 * 		sets uniforms in 'seq' to 'values[id].value'
 *
 * .seqWithValue( seq, values ) : filteredSeq
 *
 * 		filters 'seq' entries with corresponding entry in values
 *
 *
 * Methods of the top-level container (renderer factorizations):
 *
 * .setValue( gl, name, value )
 *
 * 		sets uniform with  name 'name' to 'value'
 *
 * .set( gl, obj, prop )
 *
 * 		sets uniform from object and property with same name than uniform
 *
 * .setOptional( gl, obj, prop )

 * A group of objects that receives a shared animation state.
 *
 * Usage:
 *
 * 	-	Add objects you would otherwise pass as 'root' to the
 * 		constructor or the .clipAction method of AnimationMixer.
 *
 * 	-	Instead pass this object as 'root'.
 *
 * 	-	You can also add and remove objects later when the mixer
 * 		is running.
 *
 * Note:
 *
 *  	Objects of this class appear as one object to the mixer,
 *  	so cache control of the individual objects must be done
 *  	on the group.
 *
 * Limitation:
 *
 * 	- 	The animated properties must be compatible among the
 * 		all objects in the group.
 *
 *  -	A single property can either be controlled through a
 *  	target group or directly, but not both.

 * You can also find some interesting examples made using <a href='threejs.org'>three.js</a> which is a core of whs.js, such as:

 * - <a href='http://threejs.org/examples/webgl_geometry_extrude_splines.html'>Extrude splines</a>
 *
 * Such examples can be easily implemented using whitestorm.js or it's plugins. Use `Extrude` class with <a href='https://threejs.org/docs/#api/extras/core/Shape'>THREE.Shape</a> to get extrude effect of shape defined by 2D vectors.

 * A group of objects that receives a shared animation state.
 *
 * Usage:
 *
 * 	-	Add objects you would otherwise pass as 'root' to the
 * 		constructor or the .clipAction method of AnimationMixer.
 *
 * 	-	Instead pass this object as 'root'.
 *
 * 	-	You can also add and remove objects later when the mixer
 * 		is running.
 *
 * Note:
 *
 *  	Objects of this class appear as one object to the mixer,
 *  	so cache control of the individual objects must be done
 *  	on the group.
 *
 * Limitation:
 *
 * 	- 	The animated properties must be compatible among the
 * 		all objects in the group.
 *
 *  -	A single property can either be controlled through a
 *  	target group or directly, but not both.
