// We embed our own OpenGL loader to not require user to provide their own or to have to use ours, which proved to be endless problems for users.
// Our loader is custom-generated, based on gl3w but automatically filtered to only include enums/functions that we use in this source file.
// Regenerate with: python gl3w_gen.py --imgui-dir /path/to/imgui/
