Robert Bragg 8b22b0da65 journal: avoiding some _cogl_matrix_entry_get()'s
When uploading the vertices the journal calls _cogl_matrix_entry_get()
to get a CoglMatrix for each journal entry so that it can so a software
transform. Since _cogl_matrix_entry_get() can be a performance hot-spot
and since it's trivial to keep track of the last CoglMatrixEntry seen we
now avoid repeatedly calling _cogl_matrix_entry_get() for sequential
entries with the same transform.
