6e28121ff3 cogl: include <cogl/cogl-xlib.h> for xlib specific symbols
Since Xlib.h is such a terrible citizen when it comes to symbol
namespacing it's not desirable to include Xlib.h if it is not absolutely
required. Cogl now has a standalone cogl-xlib.h that should be included
whenever any xlib specific symbols are required.

This patch updates clutter to include <cogl/cogl-xlib.h> wherever
clutter needs to use xlib specific cogl apis.

af7afc29a7 Add a Clutter-specific deprecation macro for symbols
Just like GLIB_DEPRECATED and GLIB_DEPRECATED_FOR, Clutter should have
its own wrappers for G_DEPRECATED and G_DEPRECATED_FOR, to allow opting
out of deprecation warnings.

Deprecation warnings are enabled by default, now, even when building
Clutter.

1776ac8ed5 Remove internal usage of ClutterGeometry in StageWindow
The ClutterGeometry type is a poor substitute of cairo_rectangle_int_t,
with unsigned integers for width and height to complicate matters.

Let's remove the internal usage of ClutterGeometry and switch to the
rectangle type from Cairo.

075a4ed86c x11: Improve XGenericEventCookie data allocation
https://bugzilla.gnome.org/show_bug.cgi?id=654656

Clutter may be used together with GTK+, which indirectly may use
XInput2 too, so the cookie data must persist when both are handling
events.

What happens now in a nutshell is, Clutter is only guaranteed to allocate
the cookie itself after XNextEvent(), and only frees the cookie if its
XGetEventData() call allocated the cookie data.

The X[Get|Free]EventData() calls happen now in clutter-event-x11.c as
hypothetically different event translators could also handle other set
of X Generic Events, or other libraries handling events for that matter.

2b81d90dd7 Eliminate G_CONST_RETURN
The G_CONST_RETURN define in GLib is, and has always been, a bit fuzzy.

We always used it to conform to the platform, at least for public-facing
API.

At first I assumed it has something to do with brain-damaged compilers
or with weird platforms where const was not really supported; sadly,
it's something much, much worse: it's a define that can be toggled at
compile-time to remove const from the signature of public API. This is a
truly terrifying feature that I assume was added in the past century,
and whose inception clearly had something to do with massive doses of
absynthe and opium — because any other explanation would make the
existence of such a feature even worse than assuming drugs had anything
to do with it.

Anyway, and pleasing the gods, this dubious feature is being
removed/deprecated in GLib; see bug:

  https://bugzilla.gnome.org/show_bug.cgi?id=644611

Before deprecation, though, we should just remove its usage from the
whole API. We should especially remove its usage from Cally's internals,
since there it never made sense in the first place.

223e14811c Removes Cogl from the repository
Cogl has now been split out into a standalone project with a separate
repository at git://git.gnome.org/cogl. From now on the Clutter build
will now simply look for a cogl-1.0 pkg-config file to find a suitable
Cogl library to link against at build time.

4d3bf09e60 Adds a way for Cogl to control event_mask of foreign wins
This extends cogl_onscreen_x11_set_foreign_xid to take a callback to a
function that details the event mask the Cogl requires the application
to select on foreign windows. This is required because Cogl, for
example, needs to track size changes of a window and may also in the
future want other notifications such as map/unmap.

Most applications wont need to use the foreign xwindow apis, but those
that do are required to pass a valid callback and update the event mask
of their window according to Cogl's requirements.

c55cffbb6b Moves all EGL code down from Clutter to Cogl
As was recently done for the GLX window system code, this commit moves
the EGL window system code down from the Clutter backend code into a
Cogl winsys.

Note: currently the cogl/configure.ac is hard coded to only build the GLX
winsys so currently this is only available when building Cogl as part
of Clutter.

d5022054eb 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.

94c30a4f67 x11: Provide a StageWindow::unrealize implementation
The Cogl rework removed the Window creation from realize and its
relative destruction from unrealize; the two vfuncs also managed
the mapping between Window and Stage implementation that we use
when dealing with event handling. Sadly, the missing unrealization
left entries in the mapping dangling.

Since ClutterStageX11 already provides a ::realize implementation
that sub-classes are supposed to chain up to, and the Window ↔ Stage
mapping is private to clutter-stage-x11.c, it seems only fair that
the ClutterStageX11 should also provide an ::unrealize implementation
matching the ::realize.

This implementation just removes the StageX11 pointer from the X11
Window ↔ ClutterStageX11 mapping we set up in ::realize, since the
X11 Window is managed by Cogl, now.

d6f110a4d2 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.

532b563439 Add temporary cogl-clutter.h to aid splitting out Cogl
This gives us a way to clearly track the internal Cogl API that Clutter
depends on. The aim is to split Cogl out from Clutter into a standalone
3D graphics API and eventually we want to get rid of any private
interfaces for Clutter so its useful to have a handle on that task.
Actually it's not as bad as I was expecting though.

19b8622983 Optimize culling by doing culling in eye-coordinates
This implements a variation of frustum culling whereby we convert screen
space clip rectangles into eye space mini-frustums so that we don't have
to repeatedly transform actor paint-volumes all the way into screen
coordinates to perform culling, we just have to apply the modelview
transform and then determine each points distance from the planes that
make up the clip frustum.

By avoiding the projective transform, perspective divide and viewport
scale for each point culled this makes culling much cheaper.

d3a7b7502e event: Add setters for ClutterEvent members
Creating a synthetic event requires direct access to the ClutterEvent
union members; this access does not map in bindings to high-level
languages, especially run-time bindings using GObject-Introspection.
It's also midly annoying from C, as it unnecessarily exposes the guts of
ClutterEvent - something we might want to fix in the future.

9090070a98 x11: Refresh key mapping when notified by X11
Use both the MappingNotify event and the XKB XkbMapNotify event, if

stage and input events.

9be4cfe8a9 x11/stage: Use a global Window ↔ Stage relationship
Since we need to find the stage from the X11 Window, it's better to use
a static hashmap that gets updated every time the ClutterStageX11:xwin
member is changed, instead of iterating over every stage handled by the
global ClutterStageManager singleton.

82d1e5a6ee Clean up crossing event synthesis code
Clutter should just require that the windowing system used by a backend
adds a device to the stage when the device enters, and removes it from
the stage when the device leaves; with this information, we can
synthesize every crossing event and update the device state without
other intervention from the backend-specific code.

The generation of additional crossing events for actors that are
covering the stage at the coordinates of the crossing event should be
delegated to the event processing code.

The x11 and win32 backends need to be modified to relay the enter and
leave events from the windowing system.

acf51259d2 x11: Store a back pointer to the backend in the stage
Since we access it in order to get the X11 Display pointer, it makes
sense to have the ClutterBackendX11 already available inside the
ClutterStageX11 structure, and avoid the pattern:

  ClutterBackend *backend = clutter_get_default_backend ();
  ClutterBackendX11 *backend_x11 = CLUTTER_BACKEND_X11 (backend);

which costs us a function call, a type cast and an unused variable.

e7519a149b clutter-stage-x11: Don't ensure the viewport when the window moves
When we receive a ConfigureNotify event that doesn't affect the size
of the window (only the position) then we were still calling
clutter_stage_ensure_viewport which ends up queueing a full stage
redraw. This patch makes it so that it only ensures the viewport when
the size changes as it already did for avoiding queueing a relayout.

It now also avoids setting the clipped redraws cool off period when
the window only moves under the assumption that it's only necessary
for size changes.

73cf6bd52c device: Allow enabling/disabling non-master devices
Slave and floating devices should always be disabled, and not deliver
events to the scene. It is up to the user to enable non-master devices
and handle events coming from them.

ClutterInputDevice gets a new :enabled property, defaulting to FALSE;
when a device manager creates a new device it has to set it to TRUE if
the :device-mode property is set to CLUTTER_INPUT_MODE_MASTER.

The main event queue entry point, _clutter_event_push(), will
automatically discard events coming from disabled devices.
