fff5585b5f [cogl-pango-render] Fix returning to default color after a color attribute
Since the Cogl material branch merge when changing the color of a part
using pango attributes (such as using <span color="red" /> markup)
then it wouldn't return to the default color for the rest of the
layout. pango_renderer_get_color returns NULL if there is no color
override in which case it needs to revert to the color specified as
the argument to cogl_pango_render_layout. The 'color' member of
CoglPangoRenderer has been reinstated to store that default color and
now cogl_pango_render_set_color_for_part is the only place that sets
the material color.

a1cc1f57ac [animation] Do not connect to ::completed multiple times
The clutter_actor_animate*() family of functions should only connect
to the Animation::completed signal once, during the construction of
the Animation object attached to the Actor. Otherwise, the completed
signal handler will be run multiple times, and will try to unref()
the Animation for each call -- leading to a segmentation fault.

df738d0a8c [animation] Do not unref on ::complete by default
Bug 1535 - Complete animation always unrefs ClutterAnimation (even
           after g_object_ref_sink)

Animations created through clutter_animation_new() should not
automagically unref themselves by default on ::complete. We
only want that behaviour for Animations created by the
clutter_actor_animate* family of functions, since those provide
the automagic memory management.

bd8d3f6bd8 [group] Remove long deprecated API
ClutterGroup still ships with API deprecated since 0.4. We did
promise to keep it around for a minor release cycle -- not for 3.

Since we plan on shipping 1.0 without the extra baggage of the
deprecated entry points, here's the chance to remove the accumulated
cruft.

All the removed methods and signals have a ClutterContainer
counterpart.

c3d9f0bed4 [cogl-handle] Optimize how we define cogl handles
The cogl_is_* functions were showing up quite high on profiles due to
iterating through arrays of cogl handles.

This does away with all the handle arrays and implements a simple struct
inheritance scheme. All cogl objects now add a CoglHandleObject _parent;
member to their main structures. The base object includes 2 members a.t.m; a
ref_count, and a klass pointer. The klass in turn gives you a type and
virtual function for freeing objects of that type.

Each handle type has a _cogl_##handle_type##_get_type () function
automatically defined which returns a GQuark of the handle type, so now
implementing the cogl_is_* funcs is just a case of comparing with
obj->klass->type.

Another outcome of the re-work is that cogl_handle_{ref,unref} are also much
more efficient, and no longer need extending for each handle type added to
cogl. The cogl_##handle_type##_{ref,unref} functions are now deprecated and
are no longer used internally to Clutter or Cogl. Potentially we can remove
them completely before 1.0.

04ebd6be44 [cogl] handle_automatic_blend_enable(): consider layers with invalid textures
A layer object may be instantiated when setting a combine mode, but before a
texture is associated. (e.g. this is done by the pango renderer) if this is the
case we shouldn't call cogl_texture_get_format() with an invalid cogl handle.

This patch skips over layers without a texture handle when determining if any
textures have an alpha channel.

a362a4a889 [text] Use the base class binding pool
Bug 1518 - [Patch] Widget derivied from ClutterText will crash on
           key_press_event

In clutter_text_key_press() we are using G_OBJECT_TYPE_NAME to find
out the actor's type name. However, if some widget is derived from
ClutterText, when the key press handler is called, G_OBJECT_TYPE_NAME
will return the name of the derived widget.

The default implementation should get the binding pool for the base
class.

a1a8193179 [text] Check text length in ::button-press-event
Bug 1529 - Selection bound out of sync with an empty Text actor

When the user clicks on a Text actor the cursor position and the
selection bound are set using bytes_to_offset(); if the Text is
empty, this means placing them both to 0. Setting the selection
bound to 0 means that when the user inserts a character by typing
it into the Text, the selection will be [0,1]; this will select
the first character, which will then be overwritten when typing
a new character.

The Text actor should, instead, check if there are no contents
and set the cursor position and the selection bound to -1.

The clutter_text_set_selection_bound() method should also validate
the value passed, in case it's bigger than the text lenght, or
smaller than -1.

None of this code directly related to implementing CoglTextures, and the

c4dcbb6bdb Revert "Use COGL to establish GL state for ClutterGLXTexturePixmap"
This reverts commit f9d996a460.

The change from calling glBindTexture to using the material API with
cogl_material_flush_gl_state does not always work because it doesn't
necessarily leave the active texture unit as GL_TEXTURE0. For example,
if the previously rendered texture was multi-layered then the last
thing cogl_material_flush_gl_state will do is select GL_TEXTURE1 just
to disable it.

567a96c96a [docs] More information on animation queueing
Queuing an animation on an actor cannot be done from within the
::completed signal handler, because we guarantee that the Animation
instance is valid and attached to the actor it animates for the
whole duration of the signal emission chain.

In order to queue animations you have to install an idle handler
on the main loop, and call clutter_actor_animate() inside it.

The documentation should be more clear about this caveat in the
memory management of ClutterAnimations created by the animate()
family of functions.

a93a93d007 Count timeline frames using the FPS instead of an integer interval
Bug 1495 - Timelines run 4% short

Previously the timelines were timed by calculating the interval
between each frame stored as an integer number of milliseconds so some
precision is lost. For example, requesting 60 frames per second gets
converted to 16 ms per frame which is actually 62.5 frames per
second. This makes the timeline shorter by 4%.

This patch merges the common code for timing from the timeout pools
and frame sources into an internal clutter-timeout-interval file. This
stores the interval directly as the FPS and counts the number of
frames that have been reached instead of the elapsed time.

216373047b [animation] Enhance consistency of the Animation API
The Animation API should follow this pattern:

  - functions with an Interval as part of the arguments should have
    "interval" inside their name, e.g.:

      clutter_animation_bind_interval
      clutter_animation_update_interval

  - functions dealing with property names should have "property"
    inside their name, e.g.:

      clutter_animation_has_property
      clutter_animation_unbind_property

    - unless -

  - functions dealing with a property and its value should not
    have any modifier, e.g.:

      clutter_animation_bind

The change from update_property() to update_interval() frees up
clutter_animation_update(), to be added at a later date.
