    examples: Remove explicit framebuffer allocations
    
    It used to be that cogl_framebuffer_allocate() had to be done explicitly
    but we have since made Cogl lazily allocate framebuffers when they are
    first used if they haven't already been explicitly allocated. Developers
    only need to explicitly allocate framebuffers if they are planning to
    gracefully handle any errors. In cases where the program will simply
    abort due to an allocation error they can simply rely on implicit
    allocation which will cause an abort on error.
    
    This updates the examples to not explicitly allocate the framebuffers
    since they all just abort on error anyway.
