Introduced preserved swap buffer path in GL window surface.
When a buffer swap leaves the back buffer intact we don't have to use
an FBO or PB, but can render directly to the window's back buffer,
yielding higher performance and depending less on extensions such as
multisample FBOs and FBO blitting.
