We keep the symbol in the public header, but the definition is now
private. You could not sub-class InputDevice anyway, without the
instance structure, and the lack of padding in the class made actually
implementing devices in backends really hard.
Since we have a decent XI1 and XI2 implementation, now, we should turn
the support for XInput on by default.
The actual implementation to be used at run-time is still left to be
decided by the user.
This is a lump commit that is fairly difficult to break down without
either breaking bisecting or breaking the test cases.
The new design for handling X11 event translation works this way:
- ClutterBackend::translate_event() has been added as the central
point used by a ClutterBackend implementation to translate a
native event into a ClutterEvent;
- ClutterEventTranslator is a private interface that should be
implemented by backend-specific objects, like stage
implementations and ClutterDeviceManager sub-classes, and
allows dealing with class-specific event translation;
- ClutterStageX11 implements EventTranslator, and deals with the
stage-relative X11 events coming from the X11 event source;
- ClutterStageGLX overrides EventTranslator, in order to
deal with the INTEL_GLX_swap_event extension, and it chains up
to the X11 default implementation;
- ClutterDeviceManagerX11 has been split into two separate classes,
one that deals with core and (optionally) XI1 events, and the
other that deals with XI2 events; the selection is done at run-time,
since the core+XI1 and XI2 mechanisms are mutually exclusive.
All the other backends we officially support still use their own
custom event source and translation function, but the end goal is to
migrate them to the translate_event() virtual function, and have the
event source be a shared part of Clutter core.
As the tile preview is shown or hidden when a window is dragged
around, it may stick around if the drag operation is cancelled.
Make sure that the preview is hidden in this case.

Drag operations may be cancelled, in which case the dragged window
should be restored to the position/state it had when the drag was
initialized. In order to do this for tiled states, the original
state has to be saved during the operation.
https://bugzilla.gnome.org/show_bug.cgi?id=639988
The previous tiling state of a grabbed window should be restored
if the drag operation is cancelled (by hitting the Escape key).
This might involve to meta_window_tile(), so export the function
in window-private.h.

Don't use ugly "#undef CLUTTER_DISABLE_DEPRECATED" inside source code
using deprecated symbols; we have the handy CLUTTER_COMPILATION define
that we can use as part of the "disable deprecated" conditional.
Since 1.4 the ClutterGLXTexturePixmap is just a wrapper around
ClutterX11TexturePixmap, so we can safely deprecate it. All the
functionality it provided is now effectively available from the
superclass or directly from Cogl.
The ClutterGLXTexturePixmap actor is just a wrapper around
ClutterX11TexturePixmap, since the relevant texture-from-pixmap code has
been moved down to Cogl.
The config.h header should be considered a Clutter internal header, and
the test cases (especially the interactive test cases) should strive to
never rely on internal headers.
Clutter has some platform-specific API that is accessible only if the
right backend has been compiled in. Third party applications that wish
to be portable across backends might want to use defines and other
pre-processor tricks to determine header inclusion and API usage.
While Clutter has an internal set of symbols it can use, third party
applications don't have the luxury of being able to access the config.h
generated by Clutter's configure script.
For this reason, Clutter should install a configuration header with a
series of namespaced defines that can be picked up by applications and
other third party code.
Check that the timeline is still playing before executing in
_clutter_timeline_do_tick. This fixes the possibility of receiving a
new-frame signal when stopping a timeline in response to a different
timeline's signal emission.
When drag threshold is not reached, emit_drag_begin() is not called
causing default value of priv->motion_events_enabled (false) to used to
restore motion events enabled state in Clutter. This causes drag action
to indefinitely disable motion events. The current value of motion
events enabled state is now queried on button press which guarantees
that the state will be restored with the correct value in
emit_drag_end()

Previously most of the code for cogl-program and cogl-shader was
ifdef'd out for GLES 1.1 and alternate stub definitions were
defined. This patch removes those and instead puts #ifdef's directly
in the functions that need it. This should make it a little bit easier
to maintain.

When determining whether to hash the combine constant Cogl checks the
arguments to the combine funcs to determine whether the combine
constant is used. However is was using the GLenums GL_CONSTANT_COLOR
and GL_CONSTANT_ALPHA but these are not valid values for the
CoglPipelineCombineSource enum so presumably the constant would never
get hashed. This patch makes it use Cogl's enum of
COGL_PIPELINE_COMBINE_SOURCE_CONSTANT instead.

GtkStyle has been deprecated in favor of GtkStyleContext. A full
port would involve replacing GdkColor with GdkRGBA - leave this
out for the time being.

GLES has an extension called GL_OES_mapbuffer to support mapping
buffer objects but only for writing. Cogl now has two new feature
flags to advertise whether mapping for reading and writing is
supported. Under OpenGL, these features are always set if the VBO
extension is advertised and under GLES only the write flag is set if
the GL_OES_mapbuffer extension is advertised.

In the journal code and when generating the stroke path the vertices
are generated on the fly and stored in a CoglBuffer using
cogl_buffer_map. However cogl_buffer_map is allowed to fail but it
wasn't checking for a NULL return value. In particular on GLES it will
always fail because glMapBuffer is only provided by an extension. This
adds a new pair of internal functions called
_cogl_buffer_{un,}map_for_fill_or_fallback which wrap
cogl_buffer_map. If the map fails then it will instead return a
pointer into a GByteArray attached to the context. When the buffer is
unmapped the array is copied into the buffer using
cogl_buffer_set_data.

On GLES2 there's no builtin mechanism to replace texture coordinates
with point sprite coordinates so calling glEnable(GL_POINT_SPRITE)
isn't valid. Instead the point sprite coords are implemented by using
a special builtin varying variable in GLSL.
