Detailed Description
Shader agregating surface data.
Some applications require the terrain surface data be stored in a single buffer so specific locations can be queried to determine the type. Typically this is used on a server, where lots of surface data optimised for rendering is not required, but fast cheap queries about the surface at a specific point are required.

Check whether this Shader has any effect on the given Segment.
- Returns
- true if the given Segment height range is within the range that this Shader uses. e.g. A high altitude snow shader will have no effect on low level terrain.
Implements Mercator::Shader.
