Desour 2bf1d12353 Reformat the code, using:
find -type f |  # list all regular files
  grep -E '\.(h|cpp|mm)$' |  # filter for source files
  grep -v '/mt_' |  # filter out generated files
  grep -v '/vendor/' | # and vendored GL
  grep -v '/test/image_loader_test.cpp' |  # and this file (has giant literals arrays)
  xargs -n 1 -P $(nproc) clang-format -i  # reformat everything
