When painting a ClutterText, there are two different aspects that
should be taken into account:
1. The allocated size of the actor; and
2. The reported size of the PangoLayout, which may be smaller or
bigger than (1)
When (2) is bigger than (1), ClutterText has to clip the text to
only draw at the visible contents over the actor surface. In
addition to that, ClutterText also tracks the cursor position,
which makes clipping a bit more complicated.
The current ClutterTextNode.draw() implementation assumes that
the (1) also represents (2), which is not true. This makes
clipping not work.
Fix that by assuming that the position to draw the PangoLayout
is passed as the second rectangle, and the actor size is the
first one.

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 GNOME Shell, the GNOME core user interface. It can also be run standalone, using the command "mutter", but just running plain mutter is only intended for debugging purposes.
