Adds an example cogl wayland compositor This adds an example cogl compositor to test the _cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4 output displays but doesn't support input since Cogl doesn't deal with input. It's quite a minimal example of what it takes to write a wayland compositor so could be interesting to anyone learning about wayland.

cogland: Update to the new shell interface Wayland has changed so that the shell interface now only has one function which returns a shell surface for the surface. This patch makes it create a dummy service in the same way that the wayland demo compositor does. The implementation of the shell_surface_interface for that dummy service is all no-ops.

cogland: Fix crash when frame callback is destroyed before emitted If a frame callback is destroyed before it is invoked then the struct would be freed but it would not be removed from the array of callbacks so when cogland later tried to emit the callback it would crash. This patch instead stores the callbacks in a GQueue with embedded list nodes so that they can be removed from the list in the resource destructor. That way it doesn't matter how the resource is destroyed, it will still get removed from the list. Reviewed-by: Robert Bragg <robert@linux.intel.com>

framebuffer: Add cogl_framebuffer draw methods This adds cogl_framebuffer_ apis for drawing attributes and primitives that replace corresponding apis that depend on the default CoglContext. This is part of the on going effort to adapt the Cogl api so it no longer depends on a global context variable. All the new drawing functions also take an explicit pipeline argument since we are also aiming to avoid being a stateful api like Cairo and OpenGL. Being stateless makes it easier for orthogonal components to share access to the GPU. Being stateless should also minimize any impedance miss-match for those wanting to build higher level stateless apis on top of Cogl. Note: none of the legacy, global state options such as cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or cogl_program_use() are supported by these new drawing apis and if set will simply be silently ignored.

Add -Wmissing-declarations to maintainer flags and fix problems This option to GCC makes it give a warning whenever a global function is defined without a declaration. This should catch cases were we've defined a function but forgot to put it in a header. In that case it is either only used within one file so we should make it static or we should declare it in a header. The following changes where made to fix problems: • Some functions were made static • cogl-path.h (the one containing the 1.0 API) was split into two files, one defining the functions and one defining the enums so that cogl-path.c can include the enum and function declarations from the 2.0 API as well as the function declarations from the 1.0 API. • cogl2-clip-state has been removed. This only had one experimental function called cogl_clip_push_from_path but as this is unstable we might as well remove it favour of the equivalent cogl_framebuffer_* API. • The GLX, SDL and WGL winsys's now have a private header to define their get_vtable function instead of directly declaring in the C file where it is called. • All places that were calling COGL_OBJECT_DEFINE need to have the cogl_is_whatever function declared so these have been added either as a public function or in a private header. • Some files that were not including the header containing their function declarations have been fixed to do so. • Any unused error quark functions have been removed. If we later want them we should add them back one by one and add a declaration for them in a header. • _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and made a public function with a declaration in cogl-framebuffer.h • Similarly for CoglOnscreen. • cogl_vdraw_indexed_attributes is called cogl_framebuffer_vdraw_indexed_attributes in the header. The definition has been changed to match the header. • cogl_index_buffer_allocate has been removed. This had no declaration and I'm not sure what it's supposed to do. • CoglJournal has been changed to use the internal CoglObject macro so that it won't define an exported cogl_is_journal symbol. • The _cogl_blah_pointer_from_handle functions have been removed. CoglHandle isn't used much anymore anyway and in the few places where it is used I think it's safe to just use the implicit cast from void* to the right type. • The test-utils.h header for the conformance tests explicitly disables the -Wmissing-declaration option using a pragma because all of the tests declare their main function without a header. Any mistakes relating to missing declarations aren't really important for the tests. • cogl_quaternion_init_from_quaternion and init_from_matrix have been given declarations in cogl-quaternion.h Reviewed-by: Robert Bragg <robert@linux.intel.com>

framebuffer: Add cogl_framebuffer draw methods This adds cogl_framebuffer_ apis for drawing attributes and primitives that replace corresponding apis that depend on the default CoglContext. This is part of the on going effort to adapt the Cogl api so it no longer depends on a global context variable. All the new drawing functions also take an explicit pipeline argument since we are also aiming to avoid being a stateful api like Cairo and OpenGL. Being stateless makes it easier for orthogonal components to share access to the GPU. Being stateless should also minimize any impedance miss-match for those wanting to build higher level stateless apis on top of Cogl. Note: none of the legacy, global state options such as cogl_set_depth_test_enabled(), cogl_set_backface_culling_enabled() or cogl_program_use() are supported by these new drawing apis and if set will simply be silently ignored.

The SDL example is a bit special because SDL makes it very difficult to wait on either a timeout or any file descriptors.

Adds an example cogl wayland compositor This adds an example cogl compositor to test the _cogl_wayland_texture_2d_new_from_buffer API. The compositor emulates 4 output displays but doesn't support input since Cogl doesn't deal with input. It's quite a minimal example of what it takes to write a wayland compositor so could be interesting to anyone learning about wayland.
