OGSF library - manipulating surfaces (lower level functions)
GRASS OpenGL gsurf OGSF Library
Routines to set up automatic on-the-fly recalculation of surface elevations, doing a "scaled difference" using another surface for reference
Note that we're using a true difference here, between data set values, no translations, etc.
