Georges Basile Stavracas Neto 175851eef7 clutter/stage: Simplify view setup
ClutterStage defines the 8 vertices of a frustum:

  4 ----------------------------- 5
  | \                           / |
  |  \                         /  |
  |   0 --------------------- 1   |
  |   |                       |   |
  |   |                       |   |
  |   3 --------------------- 2   |
  |  /                         \  |
  | /                           \ |
  7 ----------------------------- 6

Then, it uses triplets of vertices to create each  clipping plane.
It only sets up 4 planes (it doesn't clip based on depth), defined
by the following vertices:

 * 0 - 4 - 5
 * 1 - 5 - 6
 * 2 - 6 - 7
 * 0 - 7 - 4

The first 3 triplets are selected using the for-loop. However, the
last triplet is different, and is done out of the loop. It could
have been made simpler by using the "3 - 7 - 4" triplet.

Simplify the current code by using the suggested triplet, calculated
inside the for-loop.

Mutter

Mutter is a Wayland display server and X11 window manager and compositor library.

When used as a Wayland display server, it runs on top of KMS and libinput. It implements the compositor side of the Wayland core protocol as well as various protocol extensions. It also has functionality related to running X11 applications using Xwayland.

When used on top of Xorg it acts as a X11 window manager and compositing manager.

It contains functionality related to, among other things, window management, window compositing, focus tracking, workspace management, keybindings and monitor configuration.

Internally it uses a fork of Cogl, a hardware acceleration abstraction library used to simplify usage of OpenGL pipelines, as well as a fork af Clutter, a scene graph and user interface toolkit.

Mutter is used by, for example, GNOME Shell, the GNOME core user interface, and by Gala, elementary OS's window manager. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.

Contributing

To contribute, open merge requests at https://gitlab.gnome.org/GNOME/mutter.

The coding style used is primarily the GNU flavor of the GNOME coding style with some minor additions such as preferring stdint.h types over GLib fundamental types, and a soft 80 character line limit. However, in general, look at the file you're editing for inspiration.

Commit messages should follow the GNOME commit message guidelines. We require an URL to either an issue or a merge request in each commit.
