use [GEMglMultMatrixf] (or [GEMglMultMatrixd], but the latter will not 
give you any benefits with a current Pd)

when starting with GEMgl... you should be aware that you are doing 
openGL (there's nothing wrong with that) and that you will have to 
follow openGL conventions
a good start is to search the web for (e.g.) "glMultMatrix" and see what 
it gives you...
