Thanks Ivan, that works! Applied in 6.3cvs.

The border box still needs to be updated to count the number of lines in
the string and adjust the background box width and height accordingly. For
now you can just turn off the background box.

Bug: I notice that if you try and change the PS label background box
color or font color it just gets reset when you redraw the display.

I've little idea about Tcl/Tk so I must leave these small tasks for
someone else. The "sample" label file that comes with Spearfish has a
\n newline in it to test with.

I would hold off backporting the fixes to the 6.2.x branch until it is
all working in 6.3cvs, then do it as a single patch.
