Redundant clearing of depth and stencil buffers every render can be very
expensive, so cogl now gives control over which auxiliary buffers are
cleared.
Note: For now clutter continues to clear the color, depth and stencil buffer
each paint.

The clutter frame source tries to average out the frame deltas so that
if one frame takes 1 interval plus a little bit of extra time then the
next frame will be 1 interval minus that little bit of extra
time. Therefore the deltas can sometimes be less than the frame
interval. ClutterTimeline should accumulate these small differences
otherwise it will end up missing out frames so the total duration of
the timeline will be a lot longer.
For example this was causing test-actors to appear to run very slow.
The units in the Timeline test suite just rely on the timeline
being a timeout automatically advanced by the main loop. This
is not the case anymore, since the merge of the master-clock.
To make the test units work again we need to "emulate" the master
clock without effectively having a stage to redraw; we do this
by creating a frame source and manually advancing the timelines
we create for test purposes, using the advance_msecs() "protected"
method.
The method of ClutterTimeline that advances the timeline by a
delta (in millisecond) is going to be useful for testing the
timeline's behaviour -- and unbreak the timeline test suite that
was broken by the MasterClock merge.
With the change in commit 87e4e2 painting of hidden source actors
in ClutterClone was fixed. This commit changes the test-actor-clone
to visually verify this.
With the introduction of the map/unmap flags and the split of the
visible state from the mapped state we require that every part of
a scene graph branch is mapped in order to be painted. This breaks
the ability of a ClutterClone to paint an hidden source actor.
In order to fix this we need to introduce an override flag, similar
in spirit to the current modelview and paint opacity overrides that
Clone is already using.
The override flag, when set, will force a temporary map on a
Clone source (and its children).
ClutterContainer provides a foreach_with_internals() vfunc for
iterating over all of a container's children, be them added using
the Container API or be them internal to the container itself.
We should be using the foreach_with_internals() function instead
of the plain foreach().
When replacing the fbo_handle with a new handle it first unrefs the
old handle. This was previously a call to cogl_offscreen_unref which
silently ignored attempts to unref COGL_INVALID_HANDLE. However the
new cogl_handle_unref does check for this so we should make sure the
handle is valid to avoid the warning.
Bug 1565 - test-fbo case failed in many platform
clutter_texture_new_from_actor was broken because it created the FBO
texture but then never attached it to the material so it was never
used for rendering. The old behaviour in Clutter 0.8 was to assign the
texture directly to priv->tex. In 0.9 priv->tex is replaced with
priv->material which has a reference to the tex in layer 0. So putting
the FBO texture directly in layer 0 more closely matches the original
behaviour.
When rendering a pango layout CoglPangoRenderer now records the
operations into a list called a CoglPangoDisplayList. The entries in
the list are either glyph renderings from a texture, rectangles or
trapezoids. Multiple consecutive glyph renderings from the same glyph
cache texture are combined into a single entry. Note the
CoglPangoDisplayList has nothing to do with a GL display list.
After the display list is built it is attached to the PangoLayout with
g_object_set_qdata so that next time the layout is rendered it can
bypass rebuilding it.
The glyph rendering entries are drawn via a VBO. The VBO is attached
to the display list so it can be used multiple times. This makes the
common case of rendering a PangoLayout contained in a single texture
subsequent times usually boil down to a single call to glDrawArrays
with an already uploaded VBO.
The VBOs are accessed via the cogl_vertex_buffer API so if VBOs are
not available in GL it will resort to a fallback.
Note this will fall apart if the pango layout is altered after the
first render. I can't find a way to detect when the layout is
altered. However this won't affect ClutterText because it creates a
new PangoLayout whenever any properties are changed.
Currently ClutterModel::get_iter_at_row() ignores whether we have
a filter in place. This also extends to the get_n_rows() method.
The more consistent, more intuitive and surely more correct way to
handle a Model with a filter in place is to take into account the
presence of the filter itself -- that is:
- get_n_rows() should take into account the filter and return the
number of *filtered* rows
- get_iter_at_row() should also take the filter into account and
get the first non-filtered row
These two changes make the ClutterModel with a filter function
behave like a subset of the original Model without a filter in
place.
For instance, given a model with three rows:
- [row 0] <does not match filter>
- [row 1] <matches filter>
- [row 2] <matches filter>
- [row 3] <does not match filter>
The get_n_rows() method will return "2", since only two rows will
match the filter; the get_first_iter() method will ask for the
zero-eth row, which will return an iterator pointing to the contents
of row 1 (but the :row property of the iterator will be set to 0);
the get_last_iter() method will ask for the last row, which will
return an iterator pointing to the contents of row 2 (but the :row
property of the iterator will be set to 1).
This changes will hopefully make the Model API more consistent
in its usage whether there is a filter in place or not.
Currently, there is no way for implementations of the ClutterModel
abstract class to know whether there is a filter in place. Since
subclasses might implement some optimization in case there is no
filter present, we need a simple (and public) API to ask the model
itself.
Setting the wrap mode on the PangoLayout seems to have disappeared
during the text-actor-layout-height branch merge so this brings it
back. The test for this in test-text-cache no longer needs to be
disabled.
We also shouldn't set the width on the layout if there is no wrapping
or ellipsizing because otherwise it implicitly enables wrapping. This
only matters if the actor gets allocated smaller than its natural
size.

Bug 1484 - Redraw ClutterClone when the source changes, even for
!visible sources
Connect to ::queue-redraw on the clone source and queue a redraw.
This allows redrawing the Clone when the source changes, even in
case of a non visible source actor.

Currently, all timelines install a timeout inside the TimeoutPool
they share. Every time the main loop spins, all the timeouts are
updated. This, in turn, will usually lead to redraws being queued
on the stages.
This behaviour leads to the potential starvation of timelines and
to excessive redraws.
One lesson learned from the games developers is that the scenegraph
should be prepared in its entirety before the GL paint sequence is
initiated. This means making sure that every ::new-frame signal
handler is called before clutter_redraw() is invoked.
In order to do so a TimeoutPool is not enough: we need a master
clock. The clock will be responsible for advancing all the active
timelines created inside a scene, but only when the stage is
being redrawn.
The sequence is:
+ queue_redraw() is invoked on an actor and bubbles up
to the stage
+ if no redraw() has already been scheduled, install an
idle handler with a known priority
+ inside the idle handler:
- advance the master clock, which will in turn advance
every playing timeline by the amount of milliseconds
elapsed since the last redraw; this will make every
playing timeline emit the ::new-frame signal
- queue a relayout
- call the redraw() method of the backend
This way we trade multiple timeouts with a single frame source
that only runs if a timeline is playing and queues redraws on
the various stages.

Bug 1138 - No trackable "mapped" state
* Add a VISIBLE flag tracking application programmer's
expected showing-state for the actor, allowing us to
always ensure we keep what the app wants while tracking
internal implementation state separately.
* Make MAPPED reflect whether the actor will be painted;
add notification on a ClutterActor::mapped property.
Keep MAPPED state updated as the actor is shown,
ancestors are shown, actor is reparented, etc.
* Require a stage and realized parents to realize; this means
at realization time the correct window system and GL resources
are known. But unparented actors can no longer be realized.
* Allow children to be unrealized even if parent is realized.
Otherwise in effect either all actors or no actors are realized,
i.e. it becomes a stage-global flag.
* Allow clutter_actor_realize() to "fail" if not inside a toplevel
* Rework clutter_actor_unrealize() so internally we have
a flavor that does not mess with visibility flag
* Add _clutter_actor_rerealize() to encapsulate a somewhat
tricky operation we were doing in a couple of places
* Do not realize/unrealize children in ClutterGroup,
ClutterActor already does it
* Do not realize impl by hand in clutter_stage_show(),
since showing impl already does that
* Do not unrealize in various dispose() methods, since
ClutterActor dispose implementation already does it
and chaining up is mandatory
* ClutterTexture uses COGL while unrealizable (before it's
added to a stage). Previously this breakage was affecting
ClutterActor because we had to allow realize outside
a stage. Move the breakage to ClutterTexture, by making
ClutterTexture just use COGL while not realized.
* Unrealize before we set parent to NULL in clutter_actor_unparent().
This means unrealize() implementations can get to the stage.
Because actors need the stage in order to detach from stage.
* Update clutter-actor-invariants.txt to reflect latest changes
* Remove explicit hide/unrealize from ClutterActor::dispose since
unparent already forces those
Instead just assert that unparent() occurred and did the right thing.
* Check whether parent implements unrealize before chaining up
Needed because ClutterGroup no longer has to implement unrealize.
* Perform unrealize in the default handler for the signal.
This allows non-containers that have children to work properly,
and allows containers to override how it's done.
* Add map/unmap virtual methods and set MAPPED flag on self and
children in there. This allows subclasses to hook map/unmap.
These are not signals, because notify::mapped is better for
anything it's legitimate for a non-subclass to do.

Bug 1513 - Allow passing in ClutterPickMode to
clutter_stage_get_actor_at_pos()
At the moment, clutter_stage_get_actor_at_pos() uses CLUTTER_PICK_ALL
internally to find an actor. It would be useful to allow passing in
ClutterPickMode to clutter_stage_get_actor_at_pos(), so that the caller
can specify CLUTTER_PICK_REACTIVE as a criteria.
Bug 1516 - Does not withdraw toplevels correctly
clutter_stage_x11_hide() needs to use XWithdrawWindow(), not
XUnmapWindow().
As it stands now, if the window is already unmapped (say the WM has
minimized it), then the WM will not know that Clutter has closed the
window and will keep the window managed, showing it in the task list
and so forth.
Bug 1517 - clutter_container_foreach_with_internals()
This allows us to iterate over all children (for things like maintaining
map/realize invariants) or only children that apps added and care about.

Always compile the default keybindings into Metacity, and if we
fail to retrieve the values from GConf, use the compiled-in

having a separate arrray and code path.

This patch adds the concept of a special key for WM operations, and
the default is Super_L, which on extended PC hardware is the
"Windows key". What we do is handle the special case of a press

Super_L+<key> should still be passed to applications. In the future
we may want to also take some of these keybindings (e.g. Super+TAB)
though.
