Improves tfp performance on Nvidia

Browse Source 
Some drivers (e.g. Nvidia) get upset if you try to create multiple glx pixmaps
for the same server side pixmap object, even though you might have unique
client side names, we now avoid hitting this problem by destroying the current
glx pixmap early within clutter_glx_texture_pixmap_create_glx_pixmap.
