matrix: Add cogl_matrix_orthographic

Browse Source 
This adds an experimental cogl_matrix_orthographic() function that is
more consistent with other Cogl api by taking x_1, y_1, x_2, y_2
arguments to define the top-left and bottom-right coordinates of the
orthographic coordinates instead of OpenGL style left, right, bottom and
top values.
