Create CCG representation of subdivision surface.

Note

CCG stores dense vertices in a grid-like storage. There is no edges or faces information's for the high-poly surface.

Subdiv is expected to be refined and ready for evaluation.

CCG becomes an owner of subdiv.

TODO(sergey): Allow some user-counter or more explicit control over who owns the Subdiv. The goal should be to allow viewport GL Mesh and CCG to share same Subsurf without conflicts.
