* @param {HTMLCanvasElement} [options.view] - the canvas to use as a view, optional
* @param {boolean} [options.transparent=false] - If the render view is transparent, default false
* @param {boolean} [options.antialias=false] - sets antialias (only applicable in chrome at the moment)
* @param {boolean} [options.preserveDrawingBuffer=false] - enables drawing buffer preservation, enable this if you
* need to call toDataUrl on the webgl context
* @param {number} [options.backgroundColor=0x000000] - The background color of the rendered area
* (shown if not transparent).
* @param {boolean} [options.clearBeforeRender=true] - This sets if the renderer will clear the canvas or
* not before the new render pass.
* @param {number} [options.resolution=1] - The resolution / device pixel ratio of the renderer, retina would be 2
* @param {boolean} [options.forceCanvas=false] - prevents selection of WebGL renderer, even if such is present
* @param {boolean} [options.roundPixels=false] - If true PixiJS will Math.floor() x/y values when rendering,
* stopping pixel interpolation.
* @param {boolean} [options.forceFXAA=false] - forces FXAA antialiasing to be used over native.
* FXAA is faster, but may not always look as great **webgl only**
* @param {boolean} [options.legacy=false] - `true` to ensure compatibility with older / less advanced devices.
* If you experience unexplained flickering try setting this to true. **webgl only**

*

*
* ```js
* let renderer = PIXI.autoDetectRenderer(1024, 1024);
* let baseRenderTexture = new PIXI.BaseRenderTexture(800, 600);
* let renderTexture = new PIXI.RenderTexture(baseRenderTexture);

* sprite.position.y = 600/2;
* sprite.anchor.x = 0.5;
* sprite.anchor.y = 0.5;
*
* renderer.render(sprite, renderTexture);
* ```
*
* The Sprite in this case will be rendered using its local transform. To render this sprite at 0,0
* you can clear the transform
*
* ```js
*
* sprite.setTransform()
*
* let baseRenderTexture = new PIXI.BaseRenderTexture(100, 100);
* let renderTexture = new PIXI.RenderTexture(baseRenderTexture);

/**
* A texture stores the information that represents an image or part of an image. It cannot be added

*
* You can directly create a texture from an image and then reuse it multiple times like this :
*
* ```js
* let texture = PIXI.Texture.fromImage('assets/image.png');
* let sprite1 = new PIXI.Sprite(texture);
* let sprite2 = new PIXI.Sprite(texture);
* ```
*
* Textures made from SVGs, loaded or not, cannot be used before the file finishes processing.
* You can check for this by checking the sprite's _textureID property.
* ```js
* var texture = PIXI.Texture.fromImage('assets/image.svg');
* var sprite1 = new PIXI.Sprite(texture);
* //sprite1._textureID should not be undefined if the texture has finished processing the SVG file
* ```
* You can use a ticker or rAF to ensure your sprites load the finished textures after processing. See issue #3068.
