Neil Roberts 0c82c296bf framebuffer: Handle a NULL previous framebuffer when flushing
_cogl_framebuffer_flush_state needs to handle the case where
ctx->current_draw_buffer is NULL because this will be set in the
destructor for CoglFramebuffer if the framebuffer being destroyed is
the current framebuffer. This patch just makes it assume all state has
changed in that case.
