I'm writing a rather basic program which will have 8 colours and basic shapes with at most anti aliasing in terms of special effects. Should I concentrate on using OpenGL fixed pipeline or can I use the more modern OpenGL implementations? My guess is Raspberry Pi isn't advanced enough to allow a programmable pipeline so I should steer clear of modern things?
EDIT: Reading some more information and it seems I should also be looking into versions of the Raspberry Pi itself because it seems like different versions have different capabilities. Hmm.
