[pstricks] Setting labelFontSize causes a LaTeX font warning

[dpstory at uakron.edu]

I've found that setting labelFontSize creates a LaTeX font warning

labelFontSize=\tiny

Compiling gives

LaTeX Font Warning: Command \tiny invalid in math mode on input line 71.

in the log

the following fix seems to work

labelFontSize=\\ifmmode$\tiny$\else\tiny\fi
