Canvas.svelte Width and Height properties are being ignored.#58

In the code for `components/Canvas.svelte` the exported properties `width` and `height`, if not provided, are being set during resize to the container's width and height: ``` const resize = () => { if (width === undefined) { _width = container.clientWidth / pixelRatio; } if (height === undefined) { _height = container.clientHeight / pixelRatio; } }; ``` And if provided are used to set the size of the renderer: ``` const w = width !== undefined ? width : _width; const h = height !== undefined ? height : _height; root.renderer.setSize(w, h, false); ``` But all of this is superseded by setting the position to absolute and both the width and the height to 100% on both the container and the canvas: ``` <style> .container, canvas { position: absolute; width: 100%; height: 100%; left: 0; top: 0; } </style> ``` Why are you setting the position of these elements to absolute? Perhaps you could conditionally set the css if width && height are both undefined. Or expose the canvas so we can style it how we like.
