mutter/clutter/clutter-private.h
Øyvind Kolås e92b864dff Support for shaders in clutter. At the moment limited to drivers
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.
