[GRASS-user] Label difficulties

I fixed the bounding box size problem. It's in the cvs now. There is still a
problem, however, if the label is not aligned on center with the vector
point (this is NOT offset). When it is not aligned on center, it doesn't
match the bounding box. There needs to be more code to take care of this,
but it's really late now.

Note: if you don't click the override button, the labels will display
according to whatever is in the label file and use those defaults--reverting
the panel each time you click display. If you click the override button, it
will use whatever you set in the GUI panel and keep it showing.
