Gets rid of `orig_palette`, we now always have only 2 palettes:
1. `logical_palette`
This palette has color cycling / swapping applied but no global
effects such as brightness / fade-in.
2. `system_palette`
This palette is the actual palette used for rendering.
It is usually `logical_palette` with the global brightness setting
and fade-in/out applied.
Additionally, we now keep the k-d tree around and use it to
update single colors.
The colors that are color-cycled / swapped are never included
in the k-d tree, so the tree does not need updating on color
cycles/swaps.
In C++, globals initialization order accross translation units is not
defined. Accessing a global via a function ensures that it is initialized.
This will be needed for #7638, which will statically initialize change
handlers after the Options object has been initialized.
1. Moves more assets-related stuff from `init` to `engine/assets`.
2. Removes `SDL_audiolib` dependency from `soundsample.h`.
3. Cleans up some unused/missing includes.
4 options args are a bit unwieldy, especially when you want
to pass only the first and the last one.
With a struct, there is no need to specify the default values
for the args in between.
Done with the following script:
```ruby
Dir["Source/**/*.{h,c,cc,cpp,hpp}"].each do |path|
v = File.read(path)
next if !v.include?("uint32_t") || v.include?("cstdint")
lines = v.lines
line_num = if lines[2].start_with?(" *")
lines.index { |l| l.start_with?(" */") } + 3
else
3
end
lines.insert(line_num, "#include <cstdint>\n")
File.write(path, lines.join(""))
end
```
then fixed-up manually
Adds a custom sized type for the world tile rectagle.
This allows us to better express intent.
It also allows us to make certain globals smaller, e.g. `THEME_LOC`.
We want to be able to use unpacked MPQs on low-end platforms
(PS2/rg99/etc).
This is tricky on case-sensitive filesystems. Avoids case issues by
lowercasing all paths in the code (then we'll just need lowercased
listfiles).
