    NAME
         glXCreateGLXPixmap - create an off-screen GLX rendering area
    
    
    C SPECIFICATION
         GLXPixmap glXCreateGLXPixmap( Display *dpy,
                                       XVisualInfo *vis,
                                       Pixmap pixmap )
    
    
    PARAMETERS
         dpy     Specifies the connection to the X server.
    
         vis     Specifies the visual that defines the  structure  of
                 the   rendering   area.   It  is  a  pointer  to  an
                 XVisualInfo structure, not a visual ID or a  pointer
                 to a Visual.
    
         pixmap  Specifies the X pixmap that  will  be  used  as  the
                 front  left color buffer of the off-screen rendering
                 area.
    
    DESCRIPTION
         glXCreateGLXPixmap creates an off-screen rendering area  and
         returns its XID.  Any GLX rendering context that was created
         with respect to vis can be used to  render  into  this  off-
         screen  area.  Use glXMakeCurrent to associate the rendering
         area with a GLX rendering context.
    
         The X pixmap identified by pixmap is used as the front  left
         buffer  of  the  resulting  off-screen  rendering area.  All
         other buffers specified  by  vis,  including  color  buffers
         other than the front left buffer, are created without exter-
         nally visible names.  GLX pixmaps with double-buffering  are
         supported.  However, glXSwapBuffers is ignored by these pix-
         maps.
    
         Some implementations may not support GLX pixmaps with direct
         rendering contexts.
    
    NOTES
         XVisualInfo is defined in Xutil.h.  It is a  structure  that
         includes visual, visualID, screen, and depth elements.
    
    ERRORS
         BadMatch is generated if the depth of pixmap does not  match
         the  depth  value reported by core X11 for vis, or if pixmap
         was not created with respect to the same screen as vis.
    
         BadValue is generated if vis  is  not  a  valid  XVisualInfo
         pointer  (for  example,  if  a particular GLX implementation
         does not support this visual).
         BadPixmap is generated if pixmap is not a valid pixmap.
    
         BadAlloc is generated if the server cannot allocate the  GLX
         pixmap.
