the x11 was just the first example, there's a total of about 15 different projects OPTIONS_DEFINE= x11 x11_rawfb x11_gl2 x11_gl3 \ allegro5 gdi gdip glfw2 glfw3 \ sdl_gl2 sdl_gl3 sdl_gles2 \ sfml_gl2 sfml_gl3 there's also a few direct X projects but those do not build on FreeBSD as far as I know. Not only that but the projects are different, for example glfw, sdl and a few others support HiDPI support, that means that I can build GUI that are scaled properly based on the resolution of my screen and not look super tiny. the x11 versions doesn't support those scaling options.
