This moves us away to the array of pointers model and onto a model where each param is represented by a generic uint32_t handle. We reserve 2^16 of these handles for builtins that get generated by somewhere inside the compiler and have well-defined meanings. Generic params have handles whose meanings are defined by the driver. The primary downside to this new approach is that it moves a little bit of the work that we would normally do at compile time to draw time. On my laptop this hurts OglBatch6 by no more than 1% and doesn't seem to have any measurable affect on OglBatch7. So, while this may come back to bite us, it doesn't look too bad.
