* We commit statically linked x64 binaries for clang-format-15 for windows and
linux to make the transition easier for anyone running a linux distro that
doesn't yet support llvm 15, or in future for distros that drop support for
it.
This allows setting the CLANG_FORMAT environment variable to (e.g.)
`C:/Program Files/LLVM3.8.1/bin/clang-format.exe` and then using the
script from Git Bash on Windows. Before, it would break if there
were spaces in the path. (If a suitable clang-format were in the PATH
environment variable, though, I don't think spaces caused problems.)
* It gets a couple of things less than ideal, mostly glsl block names being on
the next line, but otherwise it's readable and stops mixed tabs/spaces which
had snuck in without checks.
