Re-export

import { Canvas } from "https://deno.land/x/skia_canvas@0.5.1/mod.ts";

Canvas is an offscreen surface that can be drawn to.

Internally it uses Skia's SkSurface and raster backend.

API is mostly compatible with the Web's OffscreenCanvas API, however we also have some non-standard methods such as save.
