Changes by Art Poskanzer and Jim Thomas in the "Bold" style

and addition of a new style "Pub" for Publication.
In the Bold style labels were considered too small. The labelsize
has been increased to 0.05 and the linewidth and framewidth have
been set to 3.The increased label sizes required a SetTitleOffset
in Y of 1.3.Also added a SetLabelOffset in Y of 0.01 and the
SetPadLeftMargin was reduced slightly.
The Pub style differs from the Bold style in having no
Title and Stat boxes and using a gray palette.
