- Can make the event buffer larger or smaller
- UI shows the current event index / size, so you know how fast it's
filling up
- Can save compressed, 10x reduction in filesize and Windows 11 explorer
actually supports ZSTD natively now so this isn't inconvenient at all

While trying to narrow down why sometimes SDL takes 20-40seconds to
initialize I built up some more profiling features.
TLDR - I still don't know why SDL is taking a long time but I've
narrowed it down to it initializing the `GAME_CONTROLLER` subsystem.
This isn't unprecedented, I found numerous github issues and articles
suggesting this is the problem:
I imagine it is hardware/OS related on some level, there are even some
recent commits in SDL that have made it worse on certain platforms. I've
had this problem myself so I will hope to get it again soon so i can
debug where in the SDL code the delay occurs and make a proper bug
report. Hopefully this helps but it's not yet confirmed -

This PR adds a feature to merc2 to update vertices. This will be needed
to efficient do effects like blerc/ripple/texture scroll. It's enabled
for blerc in jak 1 and jak 2, but with a few disclaimers:
- currently we still use the mips2c blerc implementation, which is slow
and has some "jittering" because of integer precision. When porting to
PC, there was an additional synchronization problem because blerc
overwrites the merc data as its being read by the renderers. I _think_
this wasn't an issue on PS2 because the blerc dma is higher priority
than the VIF1 DMA, but I'm not certain. Either way, I had to add a mutex
for this on PC to avoid very slight flickering/gaps. This isn't ideal
for performance, but still beats generic by a significant amount in
every place I tested. If you see merc taking 2ms to draw, it is likely
because it is stuck waiting on blerc to finish. This will go away once
blerc itself is ported to C++.
- in jak 1, we end up using generic in some cases where we could use
merc. In particular maia in village3 hut. This will be fixed later once
we can use merc in more places. I don't want to mess with the
merc/generic selection logic when we're hopefully going to get rid of it
soon.
- There is no support for ripple or texture scroll. These use generic on
jak 1, and remain broken on jak 2.
- Like with `emerc`, jak 1 has a toggle to go back to the old behavior
`*blerc-hack*`.
- In most cases, toggling this causes no visual differences. One
exception is Gol's teeth. I believe this is caused by texture coordinate
rounding issues, where generic has an additional float -> int -> float
compared to PC merc. It is very hard to notice so I'm not going to worry
about it.
Running reference tests/decompiler should now be possible on macos
(arm). Most of the changes were just cleaning up places where we were
sloppy with ifdefs, but there were two interesting ones:
- `Printer.cpp` was updated to not use a recursive function for printing
lists, to avoid stack overflow
- I replaced xxhash with another version of the same library that
supports arm (the one that comes in zstd). The interface is C instead of
C++ but it's not bad to use. I confirmed that the extractor succeeds on
jak 1 iso so it looks like this gives us the same results as the old
library.
