Twirl node

Applies a twirl warping effect similar to a black hole to the value of input UV. Very similar to Swirl node, key difference is it uses the length of a vector.

Default value for uv input will be vec2(0, 0) for shader modes PARTICLES, SKY and FOG to avoid errors becouse UV variable is not available for these modes.
