WebLike the front-to-back compositing algorithm, as soon as the pixel is opaque, no more contributions are made to the pixel. The compositing algorithm achieves this as the running weight w j stored in destination alpha reaches zero, whereas polygon antialiasing achieves this by accumulating an approximation of the α value for the resulting pixel ...
