// Render CRATER_DAT.POV to create the height_field image that
// is needed in CRATER.POV (this file). Then render this file.
// 
// ( When CRATER.POV is rendered, the output image type must be
// the same as when CRATER_DAT.POV was rendered. That is how it
// works when no image type is specified in the height_field.
// Alternatively you can specify the image type of the
// height_field object in line 23 in this file. See the
// documentation for details. )
