* clutter/cogl/cogl.h: Add cogl_fog_set() abstracting the glFog() functions and enabling the GL_FOG flag. * clutter/cogl/gl/cogl.c: Add GL implementation of cogl_fog_set(). * clutter/cogl/gles/cogl.c: Add GL/ES implementation of cogl_fog_set(). * clutter.symbols: Add new symbols. * clutter/clutter-stage.h: Add API to enable depth cueing on the stage using a linear GL fog, and to set the parameters for it (#637). * clutter/clutter-stage.c (clutter_stage_paint): Enable the GL fog if the ClutterStage:use-fog property is true. * tests/test-depth.c: Test the new stage API.
