* clutter/clutter-actor.c: (clutter_actor_paint), (clutter_actor_apply_shader): queue a redraw of actor when shader is set. * clutter/clutter-actor.h: indentation. * clutter/clutter-shader.[ch]: made the fragment and vertex shader sources properties. Report error through GError when binding shaders. * tests/test-shader.c: modified to use newer API.
