refinement for plastic deformation

attempt to have "plastic" constraint deform by re-constraining via angle, distance

deformation mode happens when breakable is set to false, but angle or distance is set

Topograb Brush Initialization

Fix unreported: Copy-pasting nodes crashes when they have an undefined type

Manipulator: comments

Manipulator: use matrix for manipulator direction

Remove type-specific axis functions.

applied some fixes that automatic analyze tool suggested

Manipulator: use matrix instead of origin

This avoids having to use manipulator-type specific functions
to set the orientation.
And will make it simpler to access transformation from Python.

Currently the matrix is still used as an offset in places.
Also per-type orientation values still need to be removed.

fix attempt for memory leak after loading FM blends in prefractured mode

note: works only with newly saved FM files, older still have unnecessary data in them which wont be automatically cleaned

Merge branch 'blender2.8' into greasepencil-object

Docs: Fix file:line links in generated API docs

Add Cone: tip soft-min should be zero

Default value should be included in range.

Merge branch '28' into custom-manipulators

Merge branch 'master' into blender2.8

Cleanup: use uint

Merge branch 'blender2.8' into greasepencil-object

Guarded allocator: Fix type in macro definition

The crash did not happen yet because we always had proper vmemh defined in
the parent scope.

Manipulator: draw options for dial

- Option to start helper angle lines based on a vector
instead of the initial mouse coords (useful for bisect & spin).
- Option to show 2x helper lines
useful when dial is used to rotate an axis value.

Manipulator: correct dial angle

Calculation was done in screen-space giving inaccuracy,
making the angle incorrect for tool code.

Cast mouse coords onto the dial plane to calculate the angle instead.

Manipulator: fix general purpose dial use

Wasn't checking own location when checking if flip is needed.
