Managed intersection data from multiprocess. Fixed ghash_pop workaround.

Added Multithreading to the intersection tests. No real performance improvement. Maybe multithreading needs to be relative to the rings, not to the nodes (double nested both?).

Calculating intersecting edges in the silhouette. (Big performance hit)

Generating Tri array for later intersection testing.

Calculate BBs for branches.

Orthographic projection now fixed as well as wrong stroke boundingbox calculation. Ring calculation might need a different approach.

Added method to remove vertices from basic meshes by remapping the v/e/l/p custom data arrays.

Overlapping parts of cross node edgecuts are now calculated.

Merge branch 'master' into soc-2017-sculpting_improvements. Keep the branch up to date.

Added memory and data to handle intersection rings. Still WIP unstable.

Added edge border calculation. Cut edge for the part is now being calculated. Added some Macros for dynamic memory allocation.

Changed Z-Vector calculation to orthographic. Makes more sense the z-vec is orthogonal to the plane the silhouette is placed on.
Added Z intersection test/approximation. Inaccurate with larger smoothing factors.

Started connecting the silhouette to existing geometry. Intersecting vertices get detected. (define DEBUG_DRAW to see)

Minor fix, crash on smoothness = 100%.

Front and backside of the silhouette are now connected.

Connected T-Intersections, Tubes, Caps front and backside. Now only transitions miss one quad.

Added Backside to the shape. Frontside and backside still need to be connected.

Added Redo. Currently the whole mesh is stored. Partial copy todo.

Added a new undonode for the silhouette operator.
Bare basics of undo now work, Redo can cause a crash and still needs to be implemented.
Fixed crash when stroke with < 3 points was drawn.

Correct missing in last commit.
