[gnome-shell/gbsneto/remove-cogl-texture-new] st: Remove deprecated cogl_texture_new()

[Georges Basile Stavracas Neto <gbsneto src gnome org>]

commit 361cc6cf921c91a9b505b7f1abbe59d5f69edb95

    st: Remove deprecated cogl_texture_new()
    
    cogl_texture_new() is used in a few places in GNOME Shell, but
    it's a deprecated Cogl function. The replacement is the less
    verbose cogl_texture_2d_new_with_size(), that is very much a
    straightforward replacement.
    
    Remove the few places where this function is used, replacing
    it by the CoglTexture2d counterpart.
