[PD] object sizes

[marius schebella]

hi cyrille,
hmm, I started working with other 3d software (blender, maya) and wanted 
to build similar stuff in gem, that is why I took a closer look into 
measures and values.
I think I would want a [rectangle 4 3] really based on (-x/2, -y/2). or 
even better with a message argument rectmode ("center" vs. "corner"). 
but anyway, I don't think gem will change, so I am fine now, knowing, 
how to set the object arguments...
thank you for your answer!
marius.
