+A snowflake. A snowflake is a type of flake which might become part of the terrain. This is used in themes in which snow flakes are enabled (see [ThemeCfg]). The image size must be 3×3. If missing, `Data/Graphics/Snow.png` is used. The default image works just fine, only override this if you really want to.

 Optional horizonally mirrored version of `Clouds.png`, `SDClouds.png`, `Flake.png` and `SDFlakeL.png`, respectively. If present, these images instead of the unmirrored ones are used when the wind blows the flakes or clouds to the left.
