cogl-shader: Prepend boilerplate for portable shaders We now prepend a set of defines to any given GLSL shader so that we can define builtin uniforms/attributes within the "cogl" namespace that we can use to provide compatibility across a range of the earlier versions of GLSL. This updates test-cogl-shader-glsl.c and test-shader.c so they no longer needs to special case GLES vs GL when splicing together its shaders as well as the blur, colorize and desaturate effects. To get a feel for the new, portable uniform/attribute names here are the defines for OpenGL vertex shaders: #define cogl_position_in gl_Vertex #define cogl_color_in gl_Color #define cogl_tex_coord_in gl_MultiTexCoord0 #define cogl_tex_coord0_in gl_MultiTexCoord0 #define cogl_tex_coord1_in gl_MultiTexCoord1 #define cogl_tex_coord2_in gl_MultiTexCoord2 #define cogl_tex_coord3_in gl_MultiTexCoord3 #define cogl_tex_coord4_in gl_MultiTexCoord4 #define cogl_tex_coord5_in gl_MultiTexCoord5 #define cogl_tex_coord6_in gl_MultiTexCoord6 #define cogl_tex_coord7_in gl_MultiTexCoord7 #define cogl_normal_in gl_Normal #define cogl_position_out gl_Position #define cogl_point_size_out gl_PointSize #define cogl_color_out gl_FrontColor #define cogl_tex_coord_out gl_TexCoord #define cogl_modelview_matrix gl_ModelViewMatrix #define cogl_modelview_projection_matrix gl_ModelViewProjectionMatrix #define cogl_projection_matrix gl_ProjectionMatrix #define cogl_texture_matrix gl_TextureMatrix And for fragment shaders we have: #define cogl_color_in gl_Color #define cogl_tex_coord_in gl_TexCoord #define cogl_color_out gl_FragColor #define cogl_depth_out gl_FragDepth #define cogl_front_facing gl_FrontFacing

keysyms: Update the macros to CLUTTER_KEY_* The keysyms defines in clutter-keysyms.h are generated from the X11 key symbols headers by doing the equivalent of a pass of sed from XK_* to CLUTTER_*. This might lead to namespace collisions, down the road. Instead, we should use the CLUTTER_KEY_* namespace. This commit includes the script, taken from GDK, that parses the X11 key symbols and generates two headers: - clutter-keysyms.h: the default included header, with CLUTTER_KEY_* - clutter-keysyms-compat.h: the compatibility header, with CLUTTER_* The compat.h header file is included if CLUTTER_DISABLE_DEPRECATED is not defined - essentially deprecating all the old key symbols. This does not change any ABI and, assuming that an application or library is not compiling with CLUTTER_DISABLE_DEPRECATED, the source compatibility is still guaranteed.

tests: abort if clutter_init fails This fixes segfaults when something goes wrong during init, but the test keeps going anyway. Except for test-easing and test-picking, these were fixed by sed magic: sed -i -s -e "s/clutter_init \?(&argc, &argv)/\ if (clutter_init (\&argc, \&argv) != CLUTTER_INIT_SUCCESS)\n\ return 1/" tests/*/*.c http://bugzilla.clutter-project.org/show_bug.cgi?id=2574

test-cogl-shader-glsl: Disable the atlas for the hand texture Atlasing needs to be disabled for the hand texture so that it can work out the step value needed to fetch a neighbouring pixel in the blur shader. If the texture ends up in the atlas then the test can't know the actual size of the texture so it looks wrong.
