Following up his previous post on the subject, Pierre has post number two about some of the new features that GD in 5.1.x has.

A simple list of the current filters: negate, grayscale, brightness, contrast, colorize, edgedetect (convolution), emboss (convolution), gaussian blur (convolution), selective blur, mean removal (convolution), smooth (convolution).

He also includes some samples of what can be done with each filter on a variety of subjects...
