Expose the get_input function of the node graph just like get_output.

Cleanup: merge arrays into edge-group struct

Use a different method of calculating path for face-holes

Instead of finding close points between islands.

use first/last points on each island to find closest islands in negative/positive directions
when searching the KD-tree.

Revert "Squashed commit of id-remap branch."

This reverts commit 35c76f6e7cab43baeebd4ec68f3a4a1802140abc.

Squashed commit of id-remap branch.

Merge branch 'master' into experimental-build

Merge branch 'master' into id-remap

Fix several issues with logic of core id-remap:

* We need to clear the 'user-one' flags and potential usercount for old_id.
* We need to consider ID usages inside a same lib as **never** being indirect ones.

Also re-enabled proxy checking for now (not sure why I commented it, think testing stuff or so...).

Bump the BVM stack size to 4095.

Currently there is no optimization for stack usage, which would ultimately
reduce the required stack size dramatically. 255 is still very low though.

Use individual node types for constructing transform matrices.

Transforms can be created as translations, rotations (euler and axis/angle)
and scale.

The UI nodes include and automatic multiplication node for convenience.

Fix id-remap looper not 'freeing' 'use-one' id usercount.

Use an explicit transform input in the array modifier node.

Transforms can only be created from translations atm.

Fix for mismatching socket type identifiers.

Have to be careful about distinguishing socket type identifiers
and bvm type identifiers.

Fix for ugly socket color because of swapped G and B ...

Improved starting point when calculating island joining paths

Merge branch 'master' into object_nodes

Some basic math operations for 4x4 matrices.

Moved math eval functions to a dedicated file.
