[pstricks] projected mathematical label with pst-solides3d

[mathias legrand]

Hi all,

as a confirmation, is it true that with the psProjection command of the 
pst-solides3d package, mathematical statements are not possible?

\psProjection[object=texte,text=$\alpha$,pos=dc,fontsize=15,plan=planA](-4.8,0)

In other words, option text=$\alpha$ will not work.

Thank you
