sorting indices back to front and discarding indices to points outside the view.

This is going to be cumbersome, VERY cumbersome, and borderline impossible if we have to consider anything else besides a single convex shape in view. I looked at how Z-Buffers are done, it's very computationally intensive and is going to be slow when done on the CPU.

restructuring all 2d rendered points into a quad-tree might be the way to go if we are going for sorting the vertices of all objects at once. Another approach would be to sort the verts of each object locally and all then reorder the entire objects. This should not be a problem as we do not expect overlapping objects.
