Mathematica's Show[ g1, g2 ] combines graphics.  GraphicsArray is
another way.  There are various ways to plot density graphics.

ListPlot3D[Table[Sin[.2x] Sin[.2y], {x, -20, 20}, {y, -20, 20}]]

ListDensityPlot[Table[Sin[.2x] Sin[.2y], {x, -20, 20}, {y, -20, 20}]]

Show[Graphics[Raster[
      Table[Sin[.2x] Sin[.2y], {x, -20, 20}, {y, -20, 20}]]]]

~DensityGraphics~[[1]] is a simple data list and plotted "specially"
but it is not very special - it's not a spline function to have to be
compatible with or something.
