/**
 * FilterFactory aims to create some SVG filters we can use when drawing an
 * image (or whatever) on a canvas.
 * Filters aren't applied with ctx.putImageData because it just overwrites the
 * underlying pixels.
 * With these filters, it's possible for example to apply some transfer maps on
 * an image without the need to apply them on the pixel arrays: the renderer
 * does the magic for us.
