globalcompositeoperation equivalent in webgl

Canvas 2D provides an option of overlapping images in different ways with the globalcompositeoperation property as shown here http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_canvas_globalcompop

Is there an option similar to this in webgl when rendering images using the texImage2D function ?
