Reverting changes to legacy polys and generic prims

Browse source 
Due to my less than eagle-like view over these functions I had assumed they were passing in a single buffer input for the changes to make buffer uploading more efficient. They aren't, which is less than ideal.

So these particular changes should be reverted. When I have some more time I'll see whether the API for these calls can be changed, because as is the multiple glSubBufferData calls could be causing stalls on some hardware.
