Fix broken normal calculation of flipped faces

added autohide filtering based on filter object vertex positions

mesh objects now use their verts and a distance, while empties (or other non-mesh objects) still
use the maximum of the object size as radius

Remove the hair modifier.

A new object type for hair will be used instead.

Cycles: light_tree_pdf() now accounts for splitting

For the MIS calculations we need to be able to calculate the
probability to sample a light using the light tree. This
did not account for splitting so if splitting was used the
probability would be wrong. This has now been fixed.

Also, if we are in PATH mode then the splitting threshold is
set to zero.

Cycles: Removed unused code

The simplified GGX code is no longer needed
with the new splitting heuristic and has
now been removed.

Separate buffer texture for hair index for each vertex.

This is needed for allowing variable length hair strands, where the hair index can not
simply be calculated from the vertex index based on a fixed-length strand.

Minor bug-fixes and optimizations.

* Change most instances of division and modulo with TILE_SIZE to bit shifting. Much more efficient since TILE_SIZE should be a
power of 2.
* Added intialization for some Mesh members. Previously had motion blur randomly toggle on and off otherwise.
* Fixed issue where voxel to tile correspondence is different between external VDBs and internal sparse grids. The fix requires
generating a new VDB grid which may be too memory intensive. Better method would be translating grids in place.
* Fixed misc OpenVDB to grid conversion issues.
