ClutterAnimator is a class for managing the animation of multiple
properties of multiple actors over time with keyframing of values.
The Animator class is meant to be used to effectively describe
animations using the ClutterScript definition format, and to construct
complex implicit animations from the ground up.

We want to set the default size without triggering the layout machinary,
so change the window creation process slightly so we start with a
640x480 window.
Due to the way the new sizing works, clutter stage must set its size in
init (to maintain old behaviour) and the properties on the X11 stage
must be initialised to 1x1 so that it actually goes ahead with the
resize.
Fixes stages that aren't user resizable and have no size set from
appearing at 1x1.
Calling clutter_actor_set_size in response to ConfigureNotify makes
setting the size of the stage racy - the most common result of which
seems to be that you can't set the stage dimensions to anything less
than 640x480.
Instead, add a first_allocation bit to the private structure of the X11
stage and force the first resize (necessary or the default stage will be
a 1x1 window).
We want the actual window geometry in clutter_stage_set_minimum_size,
not the set size. Now that the geometry function has been changed to do
what it says, use it.
Now that we have a minimum size getter on the stage object, change
get_geometry to actually always return the geometry. This fixes stages
that are set as user-resizable appearing at 1x1 size.
This will need changing in other back-ends too.
Get the current size of the stage correctly in
clutter_stage_set_minimum_size. The get_geometry StageWindow function is
not equivalent of the current size, use clutter_actor_get_size().
This adds three new texture backends.
- CoglTexture2D: This is a trimmed down version of CoglTexture2DSliced
which only supports a single texture and only works with the
GL_TEXTURE_2D target. The code is a lot simpler so it has a less
overheads than dealing with slices. Cogl will use this wherever
possible.
- CoglSubTexture: This is used to get a CoglHandle to represent a
subregion of another texture. The texture can be used as if it was a
standalone texture but it does not need to copy the resources.
- CoglAtlasTexture: This collects RGB and RGBA textures into a single
GL texture with the aim of reducing texture state changes and
increasing batching. The backend will try to manage the atlas and
may move the textures around to close gaps in the texture. By
default all textures will be placed in the atlas.
There was a typo in getting the height of the full texture to check
whether the sub region fits so that it was using the width
instead. This was causing crashes when debugging is enabled for some
apps.
When running tests under Valgrind it would be useful to pass a
suppression file for the known one-off allocations done by Clutter
and by its dependencies. This trims the output of Valgrind and
improves the ability to actually spot leaks.
The reason why we have a dummy, offscreen Window when we create the
GLX context is that GLX does not like it when you ask the context for
features if it's not made current to a Drawable. Maybe in the future
it will allow us to do so, but right now we have to make do with what
GLX offers us.
In cogl_texture_new_from_file we create and own a temporary
bitmap. There's no need to copy this data if we need to do a premult
conversion so instead it just does conversion before passing it on to
cogl_texture_new_from_bitmap.
The Cogl atlas code was using _cogl_texture_prepare_for_upload with a
NULL pointer for the dst_bmp to determine the internal format of the
texture without converting the bitmap. It needs to do this to decide
whether the texture will go in the atlas before wasting time on the
conversion. This use of the function is a little confusing so that
part of it has been split out into a new function called
_cogl_texture_determine_internal_format. The code to decide whether a
premult conversion is needed has also been split out.
Bind ctrl-backspace and ctrl-del to functions that delete a word before
or after the cursor, respectively.
Selection does not affect the deletion, but current selection is
preserved. This mimicks GTK+ functionality in GtkTextView and GtkEntry.

The SDL API is far too limited for the windowing system needs of
Clutter; the status of the SDL backend was always experimental, and
since the Windows platform is supported by a native backend there is
no point in having the SDL backend around any more.
The Win32 backend now implements the create_context method which
creates a context and binds it to a 1x1 invisible window. That way
there will always be a context bound and the features can be retrieved
without creating the default stage. This reflects the changes in
1c6ffc8..b245d55 to the GLX backend.
Instead of using g_critical() inside the create_context() implementation
of the ClutterBackendGLX we should use the passed GError, so that the
error message can bubble up to the caller.
Instead of creating the default stage during initialization we can
now safely create it whenever clutter_stage_get_default() is called.
To maintain the invariant, the default stage is immediately realized
by Clutter itself.
Since we must guarantee that Cogl has a GL context to query, it is too
late to use the "dummy Window" trick from within the get_features()
virtual function implementation.
Instead, we can create a dummy Window from create_context() itself and
leave it around - basically trading a default stage with a dummy X
window.
We need to have the dummy X window around all the time so that the
GLX context can be selected and made current.
High level toolkits might wish to construct a PangoFontDescription and
then set it directly on a ClutterText actor proxy or sub-class.
ClutterText should have a :font-description property to set (and get)
the PangoFontDescription.

Commit 92a375ab4 changed the initial value of max_texcoord_attrib_unit
to -1 so that it could disable the texture coord array for the first
texture unit when there are no texture coords used in the vbo. However
max_texcoord_attrib_unit was an unsigned value so this actually became
G_MAXUINT. The disabling loop at the bottom still worked because
G_MAXUINT+1==0 but the check for whether any texture unit is greater
than max_texcoord_attrib_unit was failing so it would always end up
disabling all texture units. This is now fixed by changing
max_texcoord_attrib_unit to be signed.
The commit ecbb7ce41a exposed some issues
when positioning the cursor with the mouse pointer: the selection is
not moved along with the cursor when inserting a single character or a
string.
Also, some freeze_notify() are called too early, leading to decoupling
from their respective thaw_notify().

The documentation for ClutterGroup behaviour when setting an explicit
size is not accurate - or, actually, it was accurate by the time
ClutterGroup was first written but has been neglected in the following
release cycles.
To avoid confusion for new users of Clutter the documentation should be
slightly expanded, mentioning the exact semantics of ClutterGroup with
regards to: preferred size, explicitly set size and how to constrain the
visible area of a ClutterGroup to an explicitly set size.
Based on a patch by: Neil Roberts <neil@linux.intel.com>
The coverage of the Behaviour sub-classes is currently abysmal. An
initial test suite for Behaviours should at least verify that the
accessors and the constructors are doing the right thing.
This initial test suite just verifies the BehaviourOpacity sub-class,
but it already bumps up the overall coverage by 2%.
When we disable the per-actor events delivery Clutter replicates the X11
implicit soft grab for motion events with off-stage. The implicit grab
is done whenever the pointer of a device leaves a window with a button
still pressed; with the implicit grab in place the window still receives
motion events even after the LeaveNotify - until the button is released.
The implicit grab is not honoured in the per-actor event deliver case,
though, so we have a mismatch between two in theory equivalent cases.
Luckily, the fix is pretty trivial: when we check for a motion event
with a stage set but without an actor set, and that has off-stage
coordinates, we arbitrarily set the source to be the stage of the event
and emit the pointer event.
