Even more optimized, lesser sampling, same effect. Thanks Alex!

used a slightly more optimized and localised heat shimmering for lava and fire

shimmering now requires larger clumps for lava

Heat Shimmering is Finally Perfect. Credit goes to Alex the Shader Wizard! Now heat shimmering happens only over lava and fire!

alex fixed heat shimmering range on lava and made the effect more prominent on small puddles :)

Alex did some great work regarding heat shimmering and having it only show on lava. The next step is to make it shimmer with smaller lava puddles, and later on hopefully shimmering over fire!

Snow Fall Update. Suggested by Deniska Caramel. Also some work on heat shimmering is being done by alex!

Made the snow and desert winds adjustabole :) Also halved their default values to 50% thanks Deniska caramel

Fixed a concatenation mistake introduce by an update on twitch extended which I was not aware of. Thanks Mimi.
