## Problem
OpenGOAL uses OpenGL 4.3.
Apple stopped upgrading OpenGL after 4.1, so the way OpenGOAL currently
works will never be playable on Macs using OpenGL.
## Solution
Luckily, downgrading to OpenGL 4.1 is not a huge change (at least it
doesn't seem like it to my untrained eyes).
## Changes
* set hints for OpenGL 4.1 instead of 4.3 for __APPLE__
* skip the OpenGL debugging callback setup for macOS (requires 4.3)
* bump down the version string for all shaders
* stop using the `binding` layout qualifier in shader code
* move the `flat` qualifier first (not sure if this is a 4.1 thing or
just Macs being more strict)
* don't mix signed and unsigned ints in shaders (not sure if this is a
4.1 thing or just Macs being more strict)
* add some hacky CPP to the Shader constructor for binding texture units
and bones buffers based on variable names in the shader code
## Results
Adds sprite distort, fixes buggy sprite rendering in progress, adds
scissoring support (used in various scrolling menus) and a very basic
implementation of `blit-displays`. This is enough to make the fade
effect in the progress menu work, along with all the menus working
properly without needing to use the REPL. This does not make screen
flipping and the filter when failing a mission work.
Added support in the decompiler for detecting `dma-buffer-add-gs-set`
and `dma-buffer-add-gs-set-flusha` and updated all of the Jak 2 code to
use it. Readability improved!
Fixes decompiler issue with `with-dma-buffer-add-bucket` not inlining
forms which broke syntax. Fixes store error warnings showing up for
non-existent stores, there is now a dedicated pass for this at the end.
I started work on making `BITBLTBUF` stuff work in the DirectRenderer,
but stopped for now because it wasn't strictly necessary. It will still
assert like before.
Work in progress minimap. Known issues:
- "path finding" doesn't appear to work - it gets stuck forever in many
cases
- some nasty patches around timer-based code
- jak arrow blending issues
- would be nice to make it higher resolution

* update progress code and fix our frame "scissoring"
* aspect ratio hacks
* expand progress tint for widescreen
* give up and comment things properly
* properly undo hacks
* optimize sprite texture flush + update shaders
* fix bugs
* change logic a bit
* crunch PNGs
* hud size fix
* clang
* remove shaders from list
* use really small alpha cut-off point for sprites
* ad `flat` to vertex shaders too
* increase cut-off very slightly
* take *2 into account
* ok for real this should be good enough
* begin work
* work
* working objs
* exporting
* it works
* before some time of day fixes
