    gl::load_with(|symbol| window.get_proc_address(symbol));

    gl::ClearColor(0.0, 1.0, 0.0, 1.0);

    while !window.is_closed() {

Platform-specific notes

Android

• To compile the examples for android, initialize the submodules, go to deps/apk-builder/apk-builder and run cargo build, then go back to glutin and call ANDROID_HOME=/path/to/sdk NDK_HOME=/path/to/ndk NDK_STANDALONE=/path/to/standalone cargo test --no-run --target=arm-linux-androideabi
• Events and vsync are not implemented
• Headless rendering doesn't work

Emscripten

• Work will start when Emscripten gets updated to LLVM 3.5 (which should happen soon)

OS/X

• Some events are not implemented
• Implementation is still work-in-progress
• Vsync not implemented

Win32

• You must call glFlush before swap_buffers, or else on Windows 8 nothing will be visible on the window
• Pixel formats are not implemented

X11

• Some input events are not implemented
• Pixel formats not implemented
• Vsync not implemented
