When resource scale is set we need to generate a scaled PangoLayout (by adding a new scale attribute, or adjusting the one we already have according the resource scale), then it has to be painted with proper scaling matrix. So everything that has to do with PangoLayout has to be in real coordinates, then clutter logical coords multiplied by resource scaling. While the actual size of the layout is the one of the PangoLayout divided by resource scale. We map the text positions to logical coords by default, while using the pixel coordinates when painting. We fall back to scale 1 when calculating preferred size if no scale is known. The pango layout will not have set a layout scale attribute, meaning it'll be 1, thus we should just assume the layout scale is 1 here. Not doing so might result in the preferred size being 0x0 meaning the actor won't be laid out properly.

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.

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.
