I've removed unnecessary allocations in the render_script and camera module update functions. I've also re-ordered a couple of things and added a few locals for readability and convenience.
In camera's update this results in a ~22% reduction. Unfortunately, the garbage produced by the many calls to
go.getis quite significant, ~5000B, so the reduction of vmath garbage by ~1500B doesn't look so great in comparison.The code is arguably a bit less readable and elegant; feel free to reject some or all of these changes.
