Added smudge tool to vertex paint. WPaint implementation coming soon. Fixed blend to use physically accurate blending model.

made flag grid also accessible through manta api. needed for liquid outflow.

Curves: Chamfer

Implemented the chamfer operator for one selected vertex and with parameters controlled through the Tool Shelf.

Calculating surface normal and direction for smudge, splash prevention, and cone painting

Merge remote-tracking branch 'origin/master' into gsoc2016-improved_extrusion

Curves: Offset operator

Added support for mouse interaction with the offset operator.
Fixed a memory leak in the get_intersections function.

Merge branch 'master' into temp-cycles-microdisplacement

Includes changes from review

Curves: Batch extend operator

Concluded the implementation of the Batch extend operator.
Though some code was reused from the Extend operator, the main algorithm is different.

made flag grid also accessible through manta api. needed for liquid outflow.

WIP: correspondence update and drawing functions

Only generate hair contacts for points that actually penetrate the mesh.

Clear debug drawing when creating new contacts.

Enable debug drawing of hair contacts.

Simple contact detection method for hair editing, using the typical BVH closest point method.

This method is just a placeholder, in the future it would be worthwhile to use Bullet collision
detection with ghost objects for this.

Also the code should eventually be abstracted a bit to make it agnostic to mesh formats, so it
can be used for BMesh as well as DNA strand data or physics simulation.

Hair edit tool settings for enabling and controlling deflection.

Unused settings, deflection is not yet implemented.

Add a cache structure for collision contact points.

This should serve as a universal interface between possible collision
detection systems (BVH, Bullet) and the various collision response systems.
Using an new data structure means that the two sides of a collision
handling feature (detection and response) can be treated independently,
reducing code dependencies and complexity.

The properties of contact points are modeled after btManifoldPoint from
Bullet and may need to be adjusted in the future.

Fix for frequent unnecessary shader recompilation during hair editing.

The depsgraph component node for invalidating the strand shader was located in
the GEOMETRY component of the object. This component by default gets tagged along
with every other object part during editing. Only standardized way of avoiding this
would be putting it in a different datablock, but the shader is very much tied to
the particular object due to the displacement function from its node tree.

For now the solution is a new component GEOMETRY_SHADER, which does not get tagged
when the ID node is tagged. It still gets regular updates from node tree changes.
This seems to be the least invasive way of avoiding unnecessary performance drops,
and can be removed and replaced easily later on without disrupting other code work.

Refactor of code, taking into account margin and storing the convex hull

Warning: Intermediate commit, this currently breaks correct packing solution computation

Updated Convex Hull data structure
