Sebastian Wick c0832b99d8 multi-texture-format: Always use the tex coords of the first plane 
The texture coordinates of all planes should be the same in theory so
using the coordinates of the first plane works.

The reason for this change is that Cogl somehow doesn't manage to get us
the correct coordinates for the 3rd plane in some circumstances. This is
really a workaround but not wrong in any way.

Intro
=====

In general, the compositor splits the window from the contents of
the window from the shape of the window. In other words, a window
has contents, and the contents of the window have a shape. This is
represented by the actor hierarchy:

 +--------------------------------------+
 | MetaWindowActor                      |
 | +----------------------------------+ |
 | | MetaSurfaceActor                 | |
 | | +------------------------------+ | |
 | | | MetaShapedTexture            | | |
 | | |                              | | |
 | | |                              | | |
 | | |                              | | |
 | | |                              | | |
 | | +------------------------------+ | |
 | +----------------------------------+ |
 +--------------------------------------+

Surfaces may also contain subsurfaces. The MetaWindowActor and
MetaSurfaceActor subclasses that will be created depend on the client
type, and the display server type.

## Subsurfaces

Additionally, there is also the case of subsurfaces: surfaces that
are child of other surfaces. That is also represented in the actor
hierarchy by having one or many MetaSurfaceActors (the subsurfaces)
added as children of a parent MetaSurfaceActor. There are no limits
to how many subsurfaces a surface may have. With subsurfaces, the
actor hierarchy looks like this:

 MetaWindowActor
  ↳ MetaSurfaceActor (surface)
     ↳ MetaShapedTexture
     ↳ MetaSurfaceActor (subsurface)
        ↳ MetaShapedTexture
        ↳ MetaSurfaceActor (sub-subsurface)
           ↳ MetaShapedTexture
     ↳ MetaSurfaceActor (subsurface)
        ↳ MetaShapedTexture

In this example, the main surface has 2 subsurfaces. One of these
subsurfaces contains a subsurface as well.

All MetaWindowActors contain at least one MetaSurfaceActor, and all
MetaSurfaceActors contain a MetaShapedTexture.

## Client and compositor

MetaWindowActor and its subclasses represent the client window's
type. A X11 client will have a MetaWindowActorX11 representing it,
and a Wayland client will have a MetaWindowActorWayland.

On the compositor side, the surface where the contents of the window
are drawn into are represented by MetaSurfaceActor subclasses. On a
Wayland session, windows are backed by a MetaSurfaceActorWayland
surface, whereas on X11 sessions, by MetaSurfaceActorX11.

XWayland windows are X11 client windows (MetaWindowActorX11) backed
by Wayland surfaces (MetaWindowActorWayland).
