[text-backface-culling] Fix width/height parameters to cogl_rectangle

Browse Source 
During the upgrade to cogl material, test-backface-culling was
switched to use cogl_rectangle instead of cogl_texture_rectangle to
draw the textures. However, cogl_rectangle takes a width and height
instead of the the top-left and bottom-right vertices so the
rectangles were being drawn in the wrong place.
