Basic image sampling node for reading interpolated color values from an Image datablock.

crash fix in FM refresh operator (null pointer access)

rigidbody type on meshisland should be taken into account now properly and be settable, also adding new constraints should happen faster now (when called in a loop)

further attempt to fix "plastic constraint" logic (external fracturing mode only)

Cleanup: Simplify depsgraph API by using the same depsnode type for each ID.

This means the user might use an invalid component key for generating dependencies,
but the only consequence is that no relation is created.

Fix sun intensity and fix a bug for some graphics cards.

implemented some special constraint breaking method further (plastic constraint breaking), for external fracturing mode

exposed per-constraint breaking angle and distance to python (for external mode only, for now)

added del guards and removed noise grids (were not used anyway)

fixed constraint restore with external fracture mode (using participants instead of jumping around in list, which messes up the iteration loop)

PSculpt: Hacky first attempt at "superbrush" mode for Adjust

Instead of inverting the brush behaviour, holding shift for the Adjust brush
will instead activate grab, making it easier to switch between these without
having to go via the buttons.

Verdict:
This only works partially. It still doesn't feel right - especially with the
Sintel rig, as the arm FK rotations feel like they go in the wrong directions.

Two-level use-count system for bvm pointer variables.

The rationale for this change is that copying variables on the bvm stack
will become necessary for compound variables (structs). In order to
efficiently keep pointers on the stack without making deep copies every
time such a variable is copied, the pointer must be a kind of shared_ptr
concept. In addition to this the stack variable itself must also be counted,
so that we have a way of detecting when it "goes out of scope", i.e. all
nodes using it have finished.

The node_counted_ptr is not a full C++ shared_ptr, because the user counting
is handled explicitly by the compiled bvm instructions. Using a std::shared_ptr
would be difficult due to the mixed levels of evaluation (compile-time constants,
storing shared_ptr on the opaque stack), and because of difficult interfacing
with C code (returning persistent plain pointers).

PSculpt: Code Cleanup - Split logic for trackball calculations into a separate callback

PSculpt: Assorted Code Cleanups

* Reshuffled callbacks
* Fixed comments
* Made dvec be stored in the data stuff

constraints transformation fix, transformations are updated on validation now

PSculpt: Code Cleanup

* Improved naming of brush callbacks
* Removed redundant/unneeded vars

first successful simulation attempt with a bigger test data set, todo... set constraints relative to object , multiply with obmat during evaluation

reverting to old mantaflow initialization

Fix compile error wwhen building without OpenVDB

Cycles: quick patch to support decoupled ray marching.

Rendering is not quite right, lots of black spots and areas, but at
least it's working.
