Describe the bug.

The image Mute.png is missing from at least DefaultDevices/_Mirror/DualShock4.

Expected behavior.

The image to be present. It is present in the non-mirrored pack.
Mirrored textures could probably be generated with a script too to ensure it always reflects the non-mirrored counterpart.
