[Therion] Legend Size

[Martin Budaj]

The latest snapshot (2007-12-06) makes this much easier. You can
change both color and size of the legend text using the following code
in the layout

code tex-map
  \legendwidth=20cm
  \legendtextcolor={\color[0 0 100]}      # RGB values 0--100
  \legendtextsize={\size[20]}
  \legendtextheadersize={\size[60]}
