Rasterized fonts saved in separate image files -- 1 image per font to enable viewing of jsMath pages by a web-browser which is missing access to TeX fonts. Sprite organization of raster fonts elivates the problem of jsmath-fonts, which is a tremendous number of images since each character has a separate image file. But such advantage comes at speed and compatibility cost. . Homepage: http://www.math.union.edu/~dpvc/jsMath
