@note This hint is experimental in its current state. There are currently

(October 2015) no corresponding WGL or GLX extensions. That makes this hint

a [hard constraint](@ref window_hints_hard) for those backends, as creation will

fail on early drivers where this flag is supported without those extensions

being listed.
