Emmanuele Bassi a146618de0 gsk: Rename set_offset() to set_anchor_point()
The naming is consistent with other scene graph libraries, as it
represents an additional translation transformation applied on top of
the provided transformation matrices.

We can also simplify the implementation by applying the translation when
we compute the world matrix.
