Sprite3DSet for Alternativa3D v8

A high performance sprite batch renderer in Alternativa3D that you can use to help render old-school sprites, globally axis-locked sprites, z-locked sprites, etc. in batches, You can use the class to create starfields (star streaks/hyperspace jump), dust, particle systems, etc. The Sprite3DSet Object3D class isn't prescriptive, since the rendering engine is seperate from the particle/material system itself. Do whatever you wish in your own material/particle system, than pump the raw numeric data into the Sprite3DSet's sprite data arrays.
