Implement restore_cmap1 routine to restore cmap1 to default colours. This is called as last step of this plot to return to default cmap1 from the gray scale cmap1 set earlier in the plot. The net effect of this change is that x16.tcl now has the default colours rather than gray scale when being run in combination with x08.tcl.
