When posting my source for a polygon breaking algorithm, I inadvertently
gave the wrong publication - a pretty lousy effort, sorry for any 
inconvenience.  The correct ref. for an algorithm to seperate a polygon
into mutually exclusive trapezoids (and shade them as well) is:

Kurt E. Brassel and Robin Fegeas,
"An Algorithm for Shading of Regions on Vector Display Devices",
Computer Graphics, Vol 13, No 2, August 1979, pp 126-133.
