Forgot to increase array size for data transfer modifier struct.

Add support for sculpt colors to the data transfer modifier

Add a paranoia check

Fixed an out of bounds read error.

fix gcc build errors

Fix last commit to handle symmetrical brushing properly

* Dyntopo now has its own brush spacing. This is a huge performance
boost for brushes with fine spacing, e.g. the clay brush.

Finished curvature rake.

wrote a fast and inaccurate distance to triangle function
for DynTopo. Profiling consistently showed it to be a bottleneck.
I've now written scalar versions of this function four times.

For now I'm committing this inaccuration version. I'm also committing
code for a vectorized version I found in a paper. Still need to rejigger
the dyntopo code to use it though.

Added per-brush DynTopo settings which are stored in a new DynTopoSettings struct.

This system is designed to inherit settings from scene dyntopo defaults
in a highly flexible way; settings can be individually overridden via the
.inherit bitmask.

At stroke time the scene settings and brush->dyntopo are merged
and stored in brush->cached_dyntopo.

Note that brush->flag has a bit flag, DYNTOPO_DISABLED, with a few
subtlies. It does not switch the PBVH back to PBVH_FACES mode, it
simply disbles dyntopo topology update. It also doesn't inherit from
any default settings. And it's the only setting
that's currently exposed in the UI.

Sculpt: Initial implementation of uniform smoothing

Add this file

Only send all vcol layers to gpu (for pbvh drawing) in a material
draw mode.

* Sculpt color layers are now properly handle by pbvh bmesh draw code.
Before only the active layer was uploaded to the GPU, now all of them
(except the autogenerated original color layer) are.
