A light that gets emitted from a single point in all directions. A common use case for this
			is to replicate the light emitted from a bare lightbulb.
			 This light can cast shadows - see [page:LightShadow] page for details.

var light = new THREE.PointLight( 0xff0000, 1, 100 );
light.position.set( 50, 50, 50 );
scene.add( light );
		
		
			[page:Integer color] - (optional) hexadecimal color of the light. Default is 0xffffff (white).
			[page:Float intensity] - (optional) numeric value of the light's strength/intensity. Default is 1.
			[page:Number distance] - Maximum range of the light. Default is 0 (no limit).
			[page:Float decay] - The amount the light dims along the distance of the light. Default is 1.
			For [page:WebGLRenderer.physicallyCorrectLights physically correct] lighting, set this to 2.
			Creates a new [name].
		
See the base [page:Light Light] class for common properties.
			The amount the light dims along the distance of the light
			In [page:WebGLRenderer.physicallyCorrectLights physically correct] mode, decay = 2 leads to physically realistic light falloff.
			Default is *1*.
		
Default mode — When distance is zero, light does not attenuate. When distance is non-zero, light will attenuate linearly from maximum intensity at the light's position down to zero at this distance from the light.
[page:WebGLRenderer.physicallyCorrectLights Physically correct] mode — When distance is zero, light will attenuate according to inverse-square law to infinite distance. When distance is non-zero, light will attenuate according to inverse-square law until near the distance cutoff, where it will then attenuate quickly and smoothly to 0. Inherently, cutoffs are not physically correct.
Default is *0.0*.
			Used to check whether this or derived classes are point lights. Default is *true*.
			You should not change this, as it used internally for optimisation.
		
			The light's power.
			In [page:WebGLRenderer.physicallyCorrectLights physically correct] mode, the luminous
			power of the light measured in lumens. Default is *4Math.PI*. 
			This is directly related to the [page:.intensity intensity] in the ratio
			
				power = intensity * 4π
			
			and changing this will also change the intensity.
		
			A [page:LightShadow] used to calculate shadows for this light.
			 The lightShadow's [page:LightShadow.camera camera]
			is set to a  [page:PerspectiveCamera] with [page:PerspectiveCamera.fov fov] of 90,
			[page:PerspectiveCamera.aspect aspect] of 1, [page:PerspectiveCamera.near near]
			clipping plane at 0.5 and	[page:PerspectiveCamera.far far] clipping plane at 500.
