Thinking about this more, perhaps the switch and driver bug workaround should be
named something like disable_default_es3? This code path is taken on more
platforms than Windows.

I suggest use "disable_es3_gl_context" instead, because in the future we will
have another switch like "disable_es3_command_buffer".
