I have managed to get lines and filled quadrilaterals on a raster in 
NT.  I basically copied  the code Marcus posted on
http://www.santafe.edu/projects/swarm/archive/list-archive.9804/0051.html
to draw ellipses but called appropriate line and polygon functions in 
win32dib.c  .   I could also give this to anyone interested.
