Moves all GLX code down from Clutter to Cogl This migrates all the GLX window system code down from the Clutter backend code into a Cogl winsys. Moving OpenGL window system binding code down from Clutter into Cogl is the biggest blocker to having Cogl become a standalone 3D graphics library, so this is an important step in that direction.

#include <X11/Xlib.h>
Declare interface types as void and remove cast macros This declares the interface types CoglFramebuffer, CoglBuffer, CoglTexture, CoglMetaTexture and CoglPrimitiveTexture as void when including the public cogl.h header so that users don't have to use lots of C type casts between instance types and interface types. This also removes all of the COGL_XYZ() type cast macros since they do nothing more than compile time type casting but it's less readable if you haven't seen that coding pattern before. Unlike with gobject based apis that use per-type macros for casting and performing runtime type checking we instead prefer to do our runtime type checking internally within the front-end public apis when objects are passed into Cogl. This greatly reduces the verbosity for users of the api and may help reduce the chance of excessive runtime type checking that can sometimes be a problem. (cherry picked from commit 248a76f5eac7e5ae4fb45208577f9a55360812a7) Since we can't break the 1.x api this version of the patch actually defines compatible NOP macros within deprecated/cogl-type-casts.h

#define __COGL_XLIB_H_INSIDE__
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.

Start clearly separating deprecated code This makes a start on clearly factoring the deprecated code of core Cogl into a deprecated/ directory. Ideally we want to get to the point where all code here can be re-worked in terms of the public 2.0 api so that it can be kept indefinitely for cogl 1.x api compatibility without cluttering the core code base itself. If we can do this then we can avoid maintaining the Cogl 1.x branches in parallel with master which would reduce the maintenance effort.

Add compiler deprecation warnings This adds compiler symbol deprecation declarations for old Cogl APIs so that users can easily see via compiler warning when they are using these symbols, and also see a hint for what the apis should be replaced with. So that users of Cogl can manage when to show these warnings this introduces a scheme borrowed from glib whereby you can declare what version of the Cogl api you are using: COGL_VERSION_MIN_REQUIRED can be defined to indicate the oldest Cogl api that the application wants to use. Cogl will only warn about deprecations for symbols that were deprecated earlier than this required version. If this is left undefined then by default Cogl will warn about all deprecations. COGL_VERSION_MAX_ALLOWED can be defined to indicate the newest api that the application uses. If the application uses symbols newer than this then Cogl will give a warning about that. This patch removes the need to maintain the COGL_DISABLE_DEPRECATED guards around deprecated symbols.

COGL_DEPRECATED_IN_1_16_FOR (cogl_xlib_renderer_handle_event)
cogl-renderer: Move the XEvent filters to be generic for all renderers Instead of having cogl_renderer_xlib_add_filter and friends there is now cogl_renderer_add_native_filter which can be used regardless of the backend. The callback function for the filter now just takes a void pointer instead of an XEvent pointer which should be interpreted differently depending on the backend. For example, on Xlib it would still be an XEvent but on Windows it could be a MSG. This simplifies the code somewhat because the _cogl_xlib_add_filter no longer needs to have its own filter list when a stub renderer is used because there is always a renderer available. cogl_renderer_xlib_handle_event has also been renamed to cogl_renderer_handle_native_event. This just forwards the event on to all of the listeners. The backend renderer is expected to register its own event filter if it wants to process the events in some way.
