Robert Bragg fd10e3a545 matrix gtype: registers a boxed type for CoglMatrix
To allow us to have gobject properties that accept a CoglMatrix value we
need to register a GType. This adds a cogl_gtype_matrix_get_type function
that will register a static boxed type called "CoglMatrix".

This adds a new section to the reference manual for GType integration
functions.
