Parallax mapping node

The Parallax Mapping node lets you create a parallax effect that displaces a Material's UVs to create the illusion of depth inside a Material.

This node is only available in shader modes SPATIAL and CANVAS ITEM.

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.
