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>

Fixes for --disable-glib This fixes some problems which were stopping --disable-glib from working properly: • A lot of the public headers were including glib.h. This shouldn't be necessary because the API doesn't expose any glib types. Otherwise any apps would require glib in order to get the header. • The public headers were using G_BEGIN_DECLS. There is now a replacement macro called COGL_BEGIN_DECLS which is defined in cogl-types.h. • A similar fix has been done for G_GNUC_NULL_TERMINATED and G_GNUC_DEPRECATED. • The CFLAGS were not including $(builddir)/deps/glib which was preventing it finding the generated glibconfig.h when building out of tree.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.

Separate out CoglPath api into sub-library This splits out the cogl_path_ api into a separate cogl-path sub-library like cogl-pango and cogl-gst. This enables developers to build Cogl with this sub-library disabled if they don't need it which can be useful when its important to keep the size of an application and its dependencies down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path have been renamed to cogl_path_{fill,stroke}. There were a few places in core cogl and cogl-gst that referenced the CoglPath api and these have been decoupled by using the CoglPrimitive api instead. In the case of cogl_framebuffer_push_path_clip() the core clip stack no longer accepts path clips directly but it's now possible to get a CoglPrimitive for the fill of a path and so the implementation of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as a shim that first gets a CoglPrimitive and uses cogl_framebuffer_push_primitive_clip instead. We may want to consider renaming cogl_framebuffer_push_path_clip to put it in the cogl_path_ namespace. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 8aadfd829239534fb4ec8255cdea813d698c5a3f) So as to avoid breaking the 1.x API or even the ABI since we are quite late in the 1.16 development cycle the patch was modified to build cogl-path as a noinst_LTLIBRARY before building cogl and link the code directly into libcogl.so as it was previously. This way we can wait until the start of the 1.18 cycle before splitting the code into a separate libcogl-path.so. This also adds shims for cogl_framebuffer_fill/stroke_path() to avoid breaking the 1.x API/ABI.

Fixes for --disable-glib This fixes some problems which were stopping --disable-glib from working properly: • A lot of the public headers were including glib.h. This shouldn't be necessary because the API doesn't expose any glib types. Otherwise any apps would require glib in order to get the header. • The public headers were using G_BEGIN_DECLS. There is now a replacement macro called COGL_BEGIN_DECLS which is defined in cogl-types.h. • A similar fix has been done for G_GNUC_NULL_TERMINATED and G_GNUC_DEPRECATED. • The CFLAGS were not including $(builddir)/deps/glib which was preventing it finding the generated glibconfig.h when building out of tree.

COGL_END_DECLS
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>
