framebuffer: split out CoglOnscreen code This factors out the CoglOnscreen code from cogl-framebuffer.c so we now have cogl-onscreen.c, cogl-onscreen.h and cogl-onscreen-private.h. Notably some of the functions pulled out are currently namespaced as cogl_framebuffer but we know we are planning on renaming them to be in the cogl_onscreen namespace; such as cogl_framebuffer_swap_buffers().

Make it possible to call swap_buffers within a frame event callback It seems like it would be quite a reasonable design for an application to immediately paint the buffer and call swap_buffers within the handler for the sync event. This previously wouldn't work. When using the GLX winsys if swap_region is called then it immediately tries to set the pending notification flag. However if this is called from the event callback then when the callback is complete it will clear the flag again and the pending notification will be lost. This patch just makes it clear the pending flag before invoking the callback so that it can be safely queued again. With any winsys that doesn't directly handle the sync event notification it would almost work except that it was iterating the live list of pending events. If the callback causes another event to be added to this list by issuing a buffer swap then the iteration would never complete and cogl_poll_dispatch would never return. This patch just makes it steal the list before iterating so that any additions will be dispatched by a later call to cogl_poll_dispatch instead.

Start to reduce dependence on glib Since we've had several developers from admirable projects say they would like to use Cogl but would really prefer not to pull in gobject,gmodule and glib as extra dependencies we are investigating if we can get to the point where glib is only an optional dependency. Actually we feel like we only make minimal use of glib anyway, so it may well be quite straightforward to achieve this. This adds a --disable-glib configure option that can be used to disable features that depend on glib. Actually --disable-glib doesn't strictly disable glib at this point because it's more helpful if cogl continues to build as we make incremental progress towards this. The first use of glib that this patch tackles is the use of g_return_val_if_fail and g_return_if_fail which have been replaced with equivalent _COGL_RETURN_VAL_IF_FAIL and _COGL_RETURN_IF_FAIL macros.

onscreen: Add CoglFrameInfo and _add_frame_callback() api Add a CoglFrameInfo object that tracks timing information for frames that are drawn. We track a frame counter and frame timing information for each CoglOnscreen. Internally a CoglFrameInfo is automatically created for each frame, delimited by cogl_onscreen_swap_buffers() or cogl_onscreen_swap_region() calls. CoglFrameInfos are delivered to applications via frame event callbacks that can be registered with a new cogl_onscreen_add_frame_callback() api. Two initial event types (dispatched on all platforms) have been defined; a _SYNC event used for throttling the frame rate of applications and a _COMPLETE event used so signify the end of a frame. Note: This new _add_frame_callback() api makes the cogl_onscreen_add_swap_complete_callback() api redundant and so it should be considered deprecated. Since the _add_swap_complete_callback() api is still experimental api, we will be looking to quickly migrate users to the new api so we can remove the old api.

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>

Move the add_swap_buffers_callback functions out of the winsys Instead of having each winsys implement its own list of callbacks the list is now just attached directly to the CoglOnscreen using code in cogl-onscreen.c. The winsys's can invoke this list of callbacks by calling _cogl_onscreen_notify_swap_buffers(). All of the winsys's would probably have a very similar implementation for this anyway and I don't think it makes much sense to try and save the cost of a list pointer in the CoglOnscreen struct.

Don't take a reference to the last used onscreen framebuffer Cogl keeps a pointer to the last used onscreen framebuffer from the context to implement the deprecated cogl_set_draw_buffer function which can take COGL_WINDOW_BUFFER as the target to use the last onscreen buffer. Previously this would also take a reference to that pointer. However that was causing a circular reference between the framebuffer and the context which makes it impossible to clean up resources properly when onscreen buffers are used. This patch instead changes it to just store the pointer and then clear the pointer during _cogl_onscreen_free as a kind of cheap weak reference. Reviewed-by: Robert Bragg <robert@linux.intel.com>

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.

Make it possible to call swap_buffers within a frame event callback It seems like it would be quite a reasonable design for an application to immediately paint the buffer and call swap_buffers within the handler for the sync event. This previously wouldn't work. When using the GLX winsys if swap_region is called then it immediately tries to set the pending notification flag. However if this is called from the event callback then when the callback is complete it will clear the flag again and the pending notification will be lost. This patch just makes it clear the pending flag before invoking the callback so that it can be safely queued again. With any winsys that doesn't directly handle the sync event notification it would almost work except that it was iterating the live list of pending events. If the callback causes another event to be added to this list by issuing a buffer swap then the iteration would never complete and cogl_poll_dispatch would never return. This patch just makes it steal the list before iterating so that any additions will be dispatched by a later call to cogl_poll_dispatch instead.

onscreen: Adds support for resizable windows This adds api to be able to request that the window system allows a given onscreen framebuffer to be resizable, and api to add and remove resize handlers to be called whenever the framebuffer does actually change size. The new functions are: cogl_onscreen_{get,set}_resizable() cogl_onscreen_{add,remove}_resize_handler() The examples cogl-hello and cogl-x11-foreign have been updated to use the new api. To smoke test how Cogl updates the viewport automatically in response to window resizes the cogl-hello test doesn't explicitly respond to resize events by setting the viewport and cogl-x11-foreign responds by setting a viewport that is offset by a quarter of the window's width/height and half the width and height of the window.

Fix flushing the stencil viewport clipping workaround There were two problems with the stencil viewport clip workaround introduced in afc5daab8: • When the viewport is changed the current clip state is not marked as dirty. That means that when the framebuffer state is next flushed it would continue to use the stencil from the previous viewport. • When the viewport is automatically updated due to the window being resized the viewport age was not incremented so the clip state wouldn't be flushed. I noticed the bugs by running cogl-sdl2-hello. This patch makes it so that the clip state is dirtied in cogl_framebuffer_set_viewport if the workaround is enabled. The automatic viewport changing code now just calls cogl_framebuffer_set_viewport instead of directly prodding the viewport values. This has the side-effect that it will also cause the journal to be flushed. This seems like the right thing to do anyway and presumably there would have been a bug before where it wouldn't have flushed the journal, although presumably this is extremely unlikely because it would have to have done a resize in the middle of painting the scene.

framebuffer: split out CoglOnscreen code This factors out the CoglOnscreen code from cogl-framebuffer.c so we now have cogl-onscreen.c, cogl-onscreen.h and cogl-onscreen-private.h. Notably some of the functions pulled out are currently namespaced as cogl_framebuffer but we know we are planning on renaming them to be in the cogl_onscreen namespace; such as cogl_framebuffer_swap_buffers().

onscreen: Adds support for resizable windows This adds api to be able to request that the window system allows a given onscreen framebuffer to be resizable, and api to add and remove resize handlers to be called whenever the framebuffer does actually change size. The new functions are: cogl_onscreen_{get,set}_resizable() cogl_onscreen_{add,remove}_resize_handler() The examples cogl-hello and cogl-x11-foreign have been updated to use the new api. To smoke test how Cogl updates the viewport automatically in response to window resizes the cogl-hello test doesn't explicitly respond to resize events by setting the viewport and cogl-x11-foreign responds by setting a viewport that is offset by a quarter of the window's width/height and half the width and height of the window.

onscreen: Add CoglFrameInfo and _add_frame_callback() api Add a CoglFrameInfo object that tracks timing information for frames that are drawn. We track a frame counter and frame timing information for each CoglOnscreen. Internally a CoglFrameInfo is automatically created for each frame, delimited by cogl_onscreen_swap_buffers() or cogl_onscreen_swap_region() calls. CoglFrameInfos are delivered to applications via frame event callbacks that can be registered with a new cogl_onscreen_add_frame_callback() api. Two initial event types (dispatched on all platforms) have been defined; a _SYNC event used for throttling the frame rate of applications and a _COMPLETE event used so signify the end of a frame. Note: This new _add_frame_callback() api makes the cogl_onscreen_add_swap_complete_callback() api redundant and so it should be considered deprecated. Since the _add_swap_complete_callback() api is still experimental api, we will be looking to quickly migrate users to the new api so we can remove the old api.
