Bug 1049 - Clutter doesn't support most GLSL uniforms (patch by Chris Lord and Neil Roberts) * README: Update release notes. * clutter/Makefile.am: * clutter/clutter-shader-types.[ch]: Add GValue types for shader values. * clutter/clutter-actor.[ch]: Update the shader API to use the newly added GValue support for GLSL shader uniform setters. * clutter/clutter-shader.[ch]: Add float and integer convenience API for single value GLSL uniform setters. * clutter/cogl/cogl-shader.h: Add new uniform setters. * clutter/cogl/gl/cogl-context.c: * clutter/cogl/gl/cogl-context.h: * clutter/cogl/gl/cogl-defines.h.in: * clutter/cogl/gl/cogl-program.c: * clutter/cogl/gl/cogl.c: Update the GL implementation of COGL to handle the GLSL uniform setters. * clutter/cogl/gles/cogl-gles2-wrapper.c: * clutter/cogl/gles/cogl-gles2-wrapper.h: * clutter/cogl/gles/cogl-internal.h: * clutter/cogl/gles/cogl-program.c: Update the GLES 2.0 implementation of COGL to handle the GLSL uniform setters. * doc/reference/clutter/clutter-sections.txt: * doc/reference/cogl/cogl-sections.txt: Update the documentation. * tests/interactive/test-fbo.c: * tests/interactive/test-shader.c: Update the shader tests.
