		<h1>[name]</h1>

		<p class="desc">
			A [link:https://webglfundamentals.org/webgl/lessons/webgl-render-to-texture.html render target] is a buffer
			where the video card draws pixels for a scene that	is being rendered in the background.
			It is used in different effects, such as applying postprocessing to a rendered image
			before displaying it on the screen.
		</p>


		<h2>Constructor</h2>


		<h3>[name]([param:Number width], [param:Number height], [param:Object options])</h3>

		<p>
		[page:Float width] - The width of the renderTarget. <br />
		[page:Float height] - The height of the renderTarget.<br />
		options - (optional object that holds texture parameters for an auto-generated target
		texture and depthBuffer/stencilBuffer booleans.

		For an explanation of the texture parameters see [page:Texture Texture]. The following are
		valid options:<br /><br />

		[page:Constant wrapS] - default is [page:Textures ClampToEdgeWrapping]. <br />
		[page:Constant wrapT] - default is [page:Textures ClampToEdgeWrapping]. <br />
		[page:Constant magFilter] - default is [page:Textures LinearFilter]. <br />
		[page:Constant minFilter] - default is [page:Textures LinearFilter]. <br />
		[page:Boolean generateMipmaps] - default is *false*.<br />
		[page:Constant format] - default is [page:Textures RGBAFormat]. <br />
		[page:Constant type] - default is [page:Textures UnsignedByteType]. <br />
		[page:Number anisotropy] - default is *1*. See [page:Texture.anisotropy]<br />
		[page:Constant encoding] - default is [page:Textures LinearEncoding]. <br />
		[page:Boolean depthBuffer] - default is *true*. <br />
		[page:Boolean stencilBuffer] - default is *false*.<br /><br />

		Creates a new [name]
		</p>

		<h2>Properties</h2>

		<h3>[property:number width]</h3>
		<p>
		The width of the render target.
		</p>

		<h3>[property:number height]</h3>
		<p>
		The height of the render target.
		</p>

		<h3>[property:Vector4 scissor]</h3>
		<p>
		A rectangular area inside the render target's viewport. Fragments that are outside the area will be discarded.
		</p>

		<h3>[property:Boolean scissorTest]</h3>
		<p>
		Indicates whether the scissor test is active or not.
		</p>

		<h3>[property:Vector4 viewport]</h3>
		<p>
		The viewport of this render target.
		</p>

		<h3>[property:Texture texture]</h3>
		<p>
		This texture instance holds the rendered pixels. Use it as input for further processing.
		</p>

		<h3>[property:Boolean depthBuffer]</h3>
		<p>
		Renders to the depth buffer. Default is true.
		</p>

		<h3>[property:Boolean stencilBuffer]</h3>
		<p>
		Renders to the stencil buffer. Default is false.
		</p>

		<h3>[property:DepthTexture depthTexture]</h3>
		<p>
		If set, the scene depth will be rendered to this texture. Default is null.
		</p>
