b526b76593 layout: Add BoxLayout, a single line layout manager
The BoxLayout layout manager implements a layout policy for arranging
children on a single line, either alongside the X axis or alongside the
Y axis.

c4b2d4ce79 layout: Report the correct size of FlowLayout
FlowLayout should compute the correct height for the assigned width when
in horizontal flow, and the correct width for the assigned height when
in vertical flow. This means pre-computing the number of lines inside
the get_preferred_width() and get_preferred_height(). We can then cache
the computed column width and row height, cache them inside the layout
and then use them when allocating the children.

5737cf869f [layout] Initial implementation of FlowLayout
FlowLayout is a layout manager that arranges its children in a
reflowing line; the orientation controls the major axis for the
layout: horizontal, for reflow on the Y axis, and vertical, for
reflow on the X axis.

8b2088a917 [layout, tests] Use variants for child packing in Box
There are three potential variants to add a child inside a Box
with a BinLayout:

  - clutter_box_pack(), a variadic argument function which
    allows passing arbitrary LayoutMeta properties and values;

  - clutter_bin_layout_add(), which uses the backpointer to
    the container from the LayoutManager and sets the layout
    properties directly without GValue (de)marshalling

  - clutter_container_add_actor() and
    clutter_bin_layout_set_alignment(), similar to the
    clutter_bin_layout_add() function above, but split in two

The test-box interactive test should exercise all three variants.

f58bdbad15 [layout] Rename Box::add to Box::pack

aaae60e178 [layout] Implement ClutterBox::add
The ClutterBox::add method is a simple wrapper around the Container
add_actor() method and the LayoutManager layout properties API. It
allows adding an actor to a Box and setting the layout properties in
one call.

If the LayoutManager used by the Box does not support layout properties
then the add() method short-circuits out.

Along with the varargs version of the method there's also a vector-based
variant, for language bindings to use.

9cccff504a [layout] Add layers to BinLayout
Each actor managed by a BinLayout policy should reside inside its
own "layer", with horizontal and vertical alignment. The :x-align
and :y-align properties of the BinLayout are the default alignment
policies, which are copied to each new "layer" when it is created.

The set_alignment() and get_alignment() methods of BinLayout can
be changed to operate on a specific "layer".

The whole machinery uses the new ChildMeta support inside the
LayoutManager base abstract class.

96859959bd [units] Be more strict in the grammar we are parsing
Current parsing of units has a number of shortcomings:
  * a number followed by trailing space (without any unit specified) was
    not recognized,
  * "5 emeralds" was parsed as 5em,
  * the way we parse the digits after the separator makes us lose
    precision for no good reason (5.0 is parsed as 5.00010014...f which
    makes g_assert_cmpfloat() fail)

Let's define a stricter grammar we can recognize and try to do so. The
description is in EBNF form, removing the optional <> which is a pain
when having to write DocBook, and using '' for the terminal symbols.

Last step, add more ClutterUnits unit test to get a better coverage of
the grammar we want to parse.

111512a2a0 [x11] Fix Stage user-initiated resize
The user-initiated resize is conflicting with the allocated size. This
happens because we change the size of the stage's X Window behind the
back of the size allocation machinery.

Instead, we should change the size of the actor whenever we receive a
ConfigureNotify event to reflect the new size of the actor.

358d7c30dc [cogl] Ensure well defined semantics for COGL_INVALID_HANDLE material layers
Fixes and adds a unit test for creating and drawing using materials with
COGL_INVALID_HANDLE texture layers.

This may be valid if for example the user has set a texture combine string
that only references a constant color.

_cogl_material_flush_layers_gl_state will bind the fallback texture for any
COGL_INVALID_HANDLE layer, later though we could explicitly check when the
current blend mode does't actually reference a texture source in which case
binding the fallback texture is redundant.

This tests drawing using cogl_rectangle, cogl_polygon and
cogl_vertex_buffer_draw.

184df2a5fa [input] Rework input device API
The input device API is split halfway thorugh the backends in a very
weird way. The data structures are private, as they should, but most
of the information should be available in the main API since it's
generic enough.

The device type enumeration, for instance, should be common across
every backend; the accessors for device type and id should live in the
core API. The internal API should always use ClutterInputDevice and
not the private X11 implementation when dealing with public structures
like ClutterEvent.

By adding accessors for the device type and id, and by moving the
device type enumeration into the core API we can cut down the amount
of symbols private and/or visible only to the X11 backends; this way
when other backends start implementing multi-pointer support we can
share the same API across the code.

9799750c03 [animation] Rework animation chaining
In order to chain up animations using clutter_actor_animate() and
friends you have to use an idle handler that guarantees that the
main loop spins at least once after the animation pointer has been
detached from the actor.

This has several drawbacks, first and foremost the fact that the
slice of the main loop for the idle handler might be starved by
other operations, like redrawing. This inevitably leads to tricks
with priorities and the like, contributing to the overall complexity.

Instead, we should guarantee that the animation instance created by
clutter_actor_animate() is valid for the ::completed signal until
it reaches its default handler; after that, the animation is detached
from the actor and destroyed. This means that it's possible to
create a new animation after the first is complete by simply using
g_signal_connect_after().

This unfortunately makes it impossible to keep a reference to the
animation pointer attached to the actor by using g_object_ref(); a
way to "fix" this would be to have a clutter_animation_attach()
and a clutter_animation_detach() pair of methods that allow attaching
any animation to an actor. This might overcomplicate what it is
the simple animation API, though, so it's currently not implemented
and left for future versions.

The test-easing interactive demo has been modified to show how
the animation queuing works by adding a command line switch that
recenters the animated actor once the first animation has ended.
