Bug#262633: xnest: Cannot get visuals for OpenGL applications

Package: xnest
Version: 4.3.0.dfsg.1-4
Severity: important

Running the following program fails under Xnest.  It works fine on the parent
server, and xdpyinfo shows that the two have identical visuals.

#include <GL/glx.h>
#include <X11/Xlib.h>
#include <assert.h>


  Display *dpy;
  int screen;
  XVisualInfo *vis=0;

  int attribs[]={GLX_RGBA,
 		 GLX_RED_SIZE,   1,
 		 GLX_BLUE_SIZE,  1,


										     dpy = XOpenDisplay(0);

										       screen = DefaultScreen(dpy);

									         vis = glXChooseVisual(dpy,screen,attribs);


										     return 0;
