@Diag wishes...

[Mark Summerfield]

I'm using lout 3.21.

1) Has anyone extended the @Diag package, e.g. with @LVLArrow,
@LVLCurveArrow, @RVRArrow, @RVRCurveArrow? @LVRArrow etc. seem to be
implemented in postscript which is beyond me. 

    @LVLArrow would go left, then vertical (down or up depending),
    then left again, i.e. a zig zag like this:

             +---- Source
             |
             |
    Dest <---+


2) I also can't see how to use a custom colour in @Node paint { },
since it only seems to accept the named @Colours. @SetColour colours
its object, but with a node you need to use paint.


Thanks.
