Neil Roberts f9f2f6bc6c Add _cogl_texture_2d_externally_modified
_cogl_texture_2d_externally_modified is a function specific to the
CoglTexture2D texture backend that should be called whenever the
contents of the texture are modified without the backend knowing about
it. It simply marks the mipmap tree as invalid.
