The Bresenham algorithms were developed originally as a means to plot lines,
circles and ellipses from the corresponding equations without using
trancendental functions (Sin, Cos, Tan, etc) thus avoiding the use of
floating point math in doing calculations. This involves a LOT less
processor time for the calculations.

One source for the basic algorithms is COMPUTER GRAPHICS by Donald Hearn and
M. Pauline Baker, Prentice Hall, 1986
