Carlos Garnacho a48a149c61 backends: Use floating point checks in MetaViewportInfo 
In these checks, it's an important detail to preserve subpixel information
in order to correctly determine whether the coordinates are inside or
outside a view.

Otherwise, small enough motion towards the left/top might get rounded
to 0, be seen as "inside the view", and the pointer coordinates be allowed
to escape the viewport constraints.

This was figured out by Pascal Nowack before me, with a difference of
minutes. Credit where credit is due.

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 of 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.
