[GRASS5] d.legend, d.zoom

done for 5.7. (code rearrangement from zoom.c more than anything else)


I figured out where the 'd.zoom zoom=' magnification option is useful:
in d.pan. I haven't added support for this in the new 'd.zoom -p' but
there isn't any reason someone couldn't.

Further cleanup of the d.zoom code still possible ...
