+ * If [antialias] is `true`, then antialiasing is performed by the browser, but
+ * only if the browser's implementation of WebGL supports antialiasing.
+ *
+ * If [depth] is `true`, then the context has a depth buffer of at least 16
+ * bits.
+ *
+ * If [premultipliedAlpha] is `true`, then the context's colors are assumed to
+ * be premultiplied. This means that color values are assumed to have  been
+ * multiplied by their alpha values. If [alpha] is `false`, then this flag is
+ * ignored.
+ *
+ * If [preserveDrawingBuffer] is `false`, then all contents of the context are
+ * cleared. If `true`, then all values will remain until changed or cleared.
