I have the debian sarge X version, which is

XFree86 Version 4.3.0.1 (Debian 4.3.0.dfsg.1-12.0.1 20050223080930)

and the 4.3.0.dfsg.1-12.0.1 xlibmesa-dri version (debian sarge).

Here is the code where we have GL_NV_texture_rectangle in
GraphicContext.cpp :

void checkExtensions(void)
     {
      const char *glExtensions = (const char
      *)glGetString(GL_EXTENSIONS);
 isTextureRectangle = (strstr(glExtensions,
   "GL_NV_texture_rectangle") != NULL);
 isTextureRectangle = isTextureRectangle ||
   (strstr(glExtensions, "GL_EXT_texture_rectangle") != NULL);
    if (isTextureRectangle)
     std::cout << "Toolkit : GL_NV_texture_rectangle or
     GL_EXT_texture_rectangle extension present, optimal texture size
     will
+be used" << std::endl;
    else
     std::cout << "Toolkit : GL_NV_texture_rectangle or
     GL_EXT_texture_rectangle extension not present, power of two
     texture
+will be used" << std::endl;
                                                                                
                                       }

What I must change to force the use of power of two texture ?

Btw, sorry for the late reply.
