I18n: Disambiguate "Mirror"

"Mirror" can mean:
- To symmetrize something (i.e. generate a new mirrored copy of it or
  edit it in a symmetric fashion).
- To flip something (i.e. invert its values along X, Y or Z axes).
- To repeat a texture in a mirrored fashion outside its bounds.

Reported by Gabriel Gazzán in #43295.
