/**
 * Native bindings to the GLX_EXT_stereo_tree extension.
 * 
 * When using stereoscopic rendering with the X composite extension, a stereo-aware GLX composite manager can be used to composite both the left and right
 * buffers of a window's backing pixmap to the left and right buffers of the root or composite overlay window to preserve the stereo effect of a
 * redirected window or any of its child windows. However, to do this, the composite manager needs a method to determine which windows have both left and
 * right buffers available without needing to walk entire window trees or be aware of other clients' GLX drawables.
 * 
 * This extension provides a new drawable tree query, which can be used by the composite manager when it begins tracking a window, and an event, which can
 * be used to listen for updates to a tracked window. This query and event provide the composite manager with a boolean value representing the stereo
 * status of an entire redirected window tree. With this information, the composite manager is able to properly choose between a stereoscopic or
 * monoscopic format when creating a GLXPixmap for a given window tree's backing pixmap.
