The DrawIcon function in the QuickDraw Auxiliary toolset is one way.  I'm not
familiar with the output ("Save as Source"?) from IconEd, but DrawIcon takes
a pointer to the icon data, an x and y location, and a code specifying how to
color the icon & how to draw it (8 choices, corresponding to what the Finder
displays for selected/not selected, online/offline, and open/closed, in all
combinations).
