isX11SurfaceDataInitialized

[Mark Wielaard]

Hi,

The isX11SurfaceDataInitialized field and new public static accessor
methods in X11GraphicsEnvironment confused me a bit at first, because it
has the X11SurfaceData and XRSurfaceData classes calling back into the
X11GraphicsEnvironment class. While not incorrect I was wondering why
not just use the static class initialization method that X11SurfaceData
was using to make sure it is only initialized once. I found the original
code easier to understand. But maybe I am missing something in the
initialization chain?

Cheers,

Mark
