[cogl/cogl-1.10] Use cogl_framebuffer_draw_rectangle api

[Neil Roberts <nroberts src gnome org>]

commit c69d92bd7058c58f1567c3eaf1094b326d937ac8

    Use cogl_framebuffer_draw_rectangle api
    
    Instead of using cogl_rectangle() this example now uses
    cogl_framebuffer_draw_rectangle(). This fixes a crash due to the example
    not pushing a current framebuffer before calling cogl_rectangle().
