 * For onscreen windows, we maintain a reference to that window's associated
 * XWindow handle here.  Offscreen surfaces have no associated Window, so for
 * those surfaces, this value will simply be zero.
 *
 *     Drawable xdrawable;
 * If a GLXDrawable has a corresponding X11 Drawable, it is stored here.  For
 * example, each GLXWindow has an associated Window and each GLXPixmap has an
 * associated Pixmap.  GLXPbuffers have no associated X11 Drawable (they are
 * pure OpenGL surfaces), so for pbuffers, this field is set to zero;
 *
 *     GLXDrawable drawable;
 * The native handle to the GLXDrawable at the core of this surface.  A
 * GLXDrawable can be a Window, GLXWindow, GLXPixmap, or GLXPbuffer.
 *
 *     AwtGraphicsConfigData *configData;
 * A pointer to the AwtGraphicsConfigData under which this surface was
