I'm trying to write some 2D text onto the screen using an OpenGL pygame 
display.  I'm having issues with the texture/raster not updating if the text 
is changed.  It will draw one correct image, and then not update it 
afterwards, however I know the functinos are being updated.  This is the 
code I'm trying to make work, I've tried rastering(this code) and texturing 
to a quad, neither was updating correctly.  Any help would be appreciated.

    def test(self):
        textureSurface = pygame.Surface((512,512))
        x,y = pygame.mouse.get_rel()
        title_font = pygame.font.Font(None, 25)

        mouseText = "MousePos x: %s, y: %s" %(x,y)
        print mouseText
        text2 = title_font.render(mouseText, 1, (250,250,250))
        textureSurface.blit(text2, (200,70))
        textureSurface = textureSurface.convert()

        #textureData = pygame.image.tostring(textureSurface, "RGBA", 1)
        #size = textureSurface.get_size()
        #glRasterPos3f(-.2,-.2,-1)
        #glDrawPixels(size[0], size[1], GL_RGBA, GL_UNSIGNED_BYTE, 
textureData)

        textureData = pygame.image.tostring(text2, "RGBA", 1)
        size = text2.get_size()
        glRasterPos3f(-.2,-.2,-1)
        glDrawPixels(size[0], size[1], GL_RGBA, GL_UNSIGNED_BYTE, 
textureData)
