Move the struct gl_renderer_interface pointer from the backends into the weston_renderer structure. The interface struct only contains function pointers that never change, so make it const. Load and initialize the GL renderer in libweston instead of in the backends, using the new weston_compositor_init_renderer() function. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de>
