We can use DllImports for OpenGL functions <= v1.1 on all platforms, including Windows. This allows us to reduce the number of required GetProcAddress calls by 474, reducing startup time and memory consumption. This setting can be turned off through Settings.Legacy.UseDllImports and UseWindowsCompatibleGL.
