providing GLSL support. * clutter/cogl/cogl.h: added rather direct binding of needed for glsl shaders. * clutter/cogl/gl/cogl-defines.h.in: * clutter/cogl/gl/cogl.c: * clutter/cogl/gles/cogl-defines.h: added stubs. * clutter/cogl/gles/cogl.c: added stubs. * clutter/glx/clutter-stage-glx.c: (clutter_stage_glx_realize): unrelated memory management sanity fix. (clutter_stage_glx_unrealize): unbind all shaders on stage unrealize. * clutter/Makefile.am: added clutter-shader.[ch] * clutter/clutter-actor.[ch]: adding shader capability to actors. * clutter/clutter-feature.h: added CLUTTER_FEATURE_SHADERS_GLSL * clutter/clutter-private.h: added stack of shaders to context. * clutter/clutter-shader.[ch]: new. * tests/Makefile.am: added shader test. * tests/test-shader.c: (frame_cb), (main): simple shader test, cycle through the inline shader with right/left mouse buttons.
