The WebGLRenderingContext.blendEquation() method of the WebGL API is used to set both the RGB blend equation and alpha blend equation to a single equation.
The WebGLRenderingContext.blendFuncSeparate() method of the WebGL API defines which function is used for blending pixel arithmetic for RGB and alpha components separately.
The WebGLRenderingContext.canvas property is a read-only reference to the HTMLCanvasElement or OffscreenCanvas object that is associated with the context. It might be null if it is not associated with a <canvas> element or an OffscreenCanvas object.
The WebGLRenderingContext.colorMask() method of the WebGL API sets which color components to enable or to disable when drawing or rendering to a WebGLFramebuffer.
