Initial implementation of the `ocean-mid`, `ocean-far` and `ocean-near` renderers for Jak 2. There's still a few things to sort out, mainly: - [x] ~Backwards compatibility with Jak 1. The only thing that currently stands in the way of that is figuring out a clean way to "un-hardcode" the texture base pointer in C++ without creating a completely separate `OceanTexture` class for Jak 2. One thing I thought of would be modifying `BucketRenderer`'s virtual `init_textures` method to also pass the `GameVersion`, but I'm not sure if there's a better way.~ - [x] ~The sudden transition from `ocean-near` to `ocean-mid`. Not sure why it's happening or how to fix it.~ - [x] The ocean has two new methods in Jak 2, `ocean::89` and `ocean::79`, one of which seems to be related to time of day sky colors. ~Even without them implemented, the end result looks quite close, so we may be able to skip them?~ `ocean::89` generates `ocean-mid` envmap textures, so it will likely be required, but will not be handled right now. Reverted the VU prologue removals because it made the tests fail.
