Brecht Van Lommel 134935a8db Sculpt: Grid based PBVH ...

* PBVH can now be created contain both from face grids or standard
  meshes. The former is much quicker to build for high res meshes.
* Moved some drawing code into pbvh (mostly for the frustum test).
* Moved ray intersection code into pbvh.
* GPU buffers also can be built from either mesh or grids now.
* Updated sculpt code to work with this. The ugly part is that there
  is now a macro for iterating over vertices, to handle both cases,
  and some duplicated code for e.g. undo.
* Smooth brush does not work yet with grids.
