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: 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.

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.

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.

object: Remove the type member of CoglObjectClass Unlike in GObject the type number for a CoglObject is entirely an internal implementation detail so there is no need to make a GQuark to make it safe to export out of the library. Instead we can just directly use a fixed pointer address as the identifier for the type. This patch makes it use the address of the class struct of the identifier. This should make it faster to do type checks because it does not need to call a function every time it wants to get the type number. Reviewed-by: Robert Bragg <robert@linux.intel.com>
