For 10 points, name this technique for providing smoother edges to lines in computer graphics.
The midposition between two elements is the key value in the Pitteway-Watkinson algorithm for performing this technique. A hardware approach to performing this technique that varies the position of the electron beam is known as a certain type of phasing. Xialon Wu offered a practical improvement on one algorithm often used in this technique; that algorithm can be implemented by giving extra preference to the position in the center of a weighting mask and is named for Bresenham. This process is usually already applied to the textures manipulated in mipmapping. When this technique is not used, artifacts like staircasing can occur, and this technique is necessary because of low-frequency sampling. Blending SRC_ALPHA and ONE_MINUS_SRC_ALPHA when doing this in OpenGL helps reduce jaggies. After performing this operation, the intensity of pixels along boundary areas is often varied.
