Normally, when they allocate a VagCmd, they do a bunch of stuff to clear
all the status bits and reset things
in particular the InitVAGCmd function does a lot
but for the stereo command, they do a lot less:
Which means that the new_stereo_command can just have random status bits
left over from whatever the last user had.
we seem to end up in a state where byte21 is set, and this causes
everything else to be wrong and off-by-one dma transfer. My guess is
that the original game avoided this bug due to lucky timing that I don't
understand.
I think the fix of just clearing byte21 is ok because there's no way
that the old value of the byte is useful after the command is
repurposed.
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.
* add ocean-vu0 mips2c and decomp ocean-texture
* vu1 texture setup
* temp
* unoptimized version working
* optimized version by default
* update ref test
