--- Comment #3 from Charles Huber <genpfault at gmail.com> ---
My guess is that the intent was to support eglChooseConfig()'s
EGL_SWAP_BEHAVIOR_PRESERVED_BIT and eglSurfaceAttrib()'s
EGL_BUFFER_PRESERVED/EGL_BUFFER_DESTROYED but currently
GetDefaultPixelFormatAttributes()'s only caller unconditionally sets
preservedSwap to false and always tries WGL_SWAP_UNDEFINED_ARB.

I'll file a bug on ANGLE's tracker and see if they like the "if preservedSwap
== false -> omit WGL_SWAP_METHOD_ARB entirely" idea.
