fd27ca7398 Mark property strings for translation
Both the nick and the blurb fields should be translatable, for UI
builders and other introspection-based tools.

ab76584965 layout-manager: Implement set_container()
Store a back pointer of the layout manager inside the container using
the GObject instance data. This introduces a change in the implementation
of ClutterLayoutManager, though it's still binary compatible.

f0b434918b docs: Add images for layout managers
It's easier to show the layout manager policy with a simple
screen shot coming from our interactive tests.

87f0b94df7 layout, docs: Fix description of Bin properties
The BinLayer and BinLayout properties name and blurb for introspection
should be slightly more descriptive.

852abbb138 layout, bin: Use ceilf() instead of casting to int
Casting a float to int to truncate it before assigning the value
to a float again is wrong. We should use ceilf() instead which
does what we want to achieve (rounding up the size to avoid
sub-pixel positioning of children).

431a63d04a [layout] Store and use the container inside BinLayout
The BinLayout should store a pointer to the Container that it is
using it as the layout manager.

This allows us to fix the API and drop the additional Container
arguments from set_alignment() and get_alignment().

This also allows us to add a ClutterBinLayout::add() method which
adds an actor and sets the alignment policies without dealing with
variadic arguments functions and GValue (de)marshalling.

a2086f1178 [layout] Add LayoutMeta
Instead of overloading ClutterChildMeta with both container and layout
metadata and delegate to every LayoutManager implementation to keep a
backpointer to the layout manager instance, we can simply subclass
ChildMeta into LayoutMeta and presto! everything works out pretty well
for everyone.

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.

b06a3293fe [layout] Notify of alignment changes in BinLayout
Emit the ::layout-changed when the BinLayout alignment policies change.

This will result in a queue_relayout() on the containers using the
BinLayout layout manager.

1061ebeac9 [layout] Add BinLayout
A BinLayout is a simple layout manager that allocates a single cell,
providing alignment on both the horizontal and vertical axis.

If the container associated to the BinLayout has more than one child,
the preferred size returned by the layout manager will be as big as
the maximum of the children preferred sizes; the allocation will be
applied to all children - but it will still depend on each child
preferred size and the BinLayout horizontal and vertical alignment
properties.

The supported alignment properties are:

  * center: align the child by centering it
  * start: align the child at the top or left border of the layout
  * end: align the child at the bottom or right border of the layout
  * fill: expand the child to fill the size of the layout
  * fixed: let the child position itself
