- * The properties of a WebGL rendering context.
- *
- * If [alpha] is `true`, then the context has an alpha channel.
- *
- * 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.
- *
- * If [stencil] is `true`, then the context has a stencil buffer of at least 8
- * bits.
