* clutter/clutter-private.h: Remove inclusion of backend-specific headers; update the main context object; add the declarations for the event queue functions. * clutter/clutter-backend.[ch]: Add the abstract ClutterBackend object, which holds backend-specific settings, the main stage, and the event queue. Every backend must implement a subclass of ClutterBackend and ClutterStage. * clutter/clutter-feature.c: Protect the GLX specific calls behing #ifdef HAVE_CLUTTER_GLX. * clutter/clutter-actor.c: * clutter/clutter-group.c: * clutter/clutter-clone-texture.c: Include GL/gl.h * clutter/clutter-event.[ch]: Update public API and implement the event queue private API; hold a reference on the event objects; move out the keysym-to-unicode table; add the new event types. * clutter/clutter-color.h: Include clutter-fixed.h * clutter/clutter-main.c: Update API; get the main stage from the backend object; process the event received from the queue; lock/unlock the main mutex if we have one; move the initialisation process sooner in the init sequence, in order to have the backend object when we check for options; call the backed vfuncs in the pre/post parse hooks. * clutter/clutter-stage.c: Make ClutterStage and abstract class, implemented by the backends. * clutter/clutter/glx/clutter-glx.h: * clutter/clutter/glx/clutter-backend-glx.[ch]: * clutter/clutter/glx/clutter-event-glx.c: * clutter/clutter/glx/clutter-stage-glx.[ch]: * clutter/clutter/glx/Makefile.am: Add the GLX backend. * clutter/clutter/egl/clutter-backend-egl.[ch]: * clutter/clutter/egl/clutter-event-egl.c: * clutter/clutter/egl/clutter-stage-egl.[ch]: * clutter/clutter/egl/Makefile.am: Add the stub for a EGL backend. * examples/*.c: Update for the new API.
