This adds support for multisample rendering to offscreen framebuffers. After an offscreen framebuffer is first instantiated using cogl_offscreen_new_to_texture() it is then possible to use cogl_framebuffer_set_samples_per_pixel() to request multisampling before the framebuffer is allocated. This also adds cogl_framebuffer_resolve_samples() for explicitly resolving point samples into pixels. Even though we currently only support the IMG_multisampled_render_to_texture extension which doesn't require an explicit resolve, the plan is to also support the EXT_framebuffer_multisample extension which uses the framebuffer_blit extension to issue an explicit resolve.
