Clean up CoglTexturePixmapX11 first

Browse Source 
With currently distributed versions of Mesa, calling XFreePixmap()
before glxDestroyPixmap() will cause an X error from DRI. So, we
need to make sure that we get rid of the CoglTexturePixmapX11 before
we XFreePixmap().

clutter_x11_texture_pixmap_dispose(): Call
 clutter_x11_texture_pixmap_set_pixmap() instead of using XFreePixmap
 directly so that we leverage the text-clearing hack and destroy
 things in the right order.

clutter_x11_texture_pixmap_set_pixmap(): Don't do a pointless roundtrip
 and trap a pointless error when setting pixmap to None.

clutter_x11_texture_pixmap_set_pixmap(): Free damage resources when
 we are setting Pixmap to None.

clutter_x11_texture_pixmap_set_window(): When setting a new window
 or setting the window to None, immedediately  call
 cluter_x11_texture_pixmap_set_pixmap(). This means that set_window(None)
 immediately will free any referenced resources related to the window.
