Detailed Description

Interface for mesh data sources.

Mesh is a collection of vertices and faces in 2D or 3D space

vertex - XY(Z) point (in the mesh's coordinate reference system)
faces - sets of vertices forming a closed shape - typically triangles or quadrilaterals

Base on the underlying data provider/format, whole mesh is either stored in memory or read on demand

Note: The API is considered EXPERIMENTAL and can be changed without a notice
