Importantly, reversed mul_serie_m3 argument order (so it matches the m4 function)

Requires some more intense testing.

Opted to keep includes if they are used indirectly (even if removing is possible).

Summary:
The title actually says it all, it's just possible to
have independent free handles for mask splines. Also
it's now possible to have aligned handles displayed
as independent handles.
Required changes in quite a few places, but they're
rather straightforward.
From user perspective there's one really visible change
which is removed Handle Type menu from the panel. With
asymmetric handles it's not clear which handle type to
display there. So now the only way to change handle type
is via V-key menu.
Rewrote normal evaluation function to make it deal
with new type of handles we support. Now it works in
the following way:
- Offset the original spline by maximal weight
- Calculate vector between corresponding U positions
on offset and original spline
- Normalize this vector.
Seems to be giving more adequate results and doesn't
tend to self-intersect as much as old behavior used to,
There're still some changes which needed to be done, but
which are planned for further patch:
- Support colors and handle size via themes.
- Make handles color-coded, just the same as done for
regular bezier splines in 3D viewport.
Additional changes to make roto workflow even better:
- Use circles to draw handles
- Support AA for handles
- Change click-create-drag to change curvature of the
spline instead of adjusting point position.

depsgraph updates.
Material datablocks were localized by first making a regular datablock
copy, which always gets inserted into the bmain list, and then removing
it again from bmain.
Problem is that this localization happens in preview threads, which can
run while the depsgraph is also updating GPU materials. In case the
copying of materials takes any amount of time, this can cause the
depsgraph call to material_changed to use an invalid, localized material
and access invalid GPUMaterial lists which have already been freed for
the actual material.
Solution is to not add localized datablocks to the bmain lists in the
first place. bmain should be totally immutable during preview or render
threads.

So now it's possible to copy-paste splines between layers.
Implementation is pretty much straightforward and duplicates
some logic which we've got in sequencer/tracking clipboards.
Will work on a common routine for clipboards later, for now
it's not so much crucial to have.

Previously this only worked for some datablocks relevant to rendering, now it
can be used to detect if any type of datablock was added or removed (but not
yet to detect if it was modified, we need many more depsgraph tags for that).
Most of the changes are some function parameter changes, the important parts
are the DAG_id_type_tag calls.

rename change/is_change/is_changed/modified -> changed
also use bools over int/short/char and once accidental float.

This makes a number of operators no longer ask for confirmation, rather it will
show an info message after performing the operation. Ref T37422 for decision. In
particular, these were changed:
* Delete objects, bones, keyframes, masks, mask curves, motion tracks, markers.
* Clear and delete keyframes in the 3D view.
* Align bone to parents.
* Separate bones from armature.
* Group/ungroup metastrips in sequencer.
* Copy/paste objects to/from buffer.

This commit includes all the changes made for plane tracker
in tomato branch.
Movie clip editor changes:
- Artist might create a plane track out of multiple point
tracks which belongs to the same track (minimum amount of
point tracks is 4, maximum is not actually limited).
When new plane track is added, it's getting "tracked"
across all point tracks, which makes it stick to the same
plane point tracks belong to.
- After plane track was added, it need to be manually adjusted
in a way it covers feature one might to mask/replace.
General transform tools (G, R, S) or sliding corners with
a mouse could be sued for this. Plane corner which
corresponds to left bottom image corner has got X/Y axis
on it (red is for X axis, green for Y).
- Re-adjusting plane corners makes plane to be "re-tracked"
for the frames sequence between current frame and next
and previous keyframes.
- Kayframes might be removed from the plane, using Shit-X
(Marker Delete) operator. However, currently manual
re-adjustment or "re-track" trigger is needed.
Compositor changes:
- Added new node called Plane Track Deform.
- User selects which plane track to use (for this he need
to select movie clip datablock, object and track names).
- Node gets an image input, which need to be warped into
the plane.
- Node outputs:
* Input image warped into the plane.
* Plane, rasterized to a mask.
Masking changes:
- Mask points might be parented to a plane track, which
makes this point deforming in a way as if it belongs
to the tracked plane.

crashes Blender
existing code was very stupid.
- all ID pointers for clipboard strips are handled uniformly.
- clipboard stores a duplicate ID pointer which are restored on paste.
- restoring pointers...
-- use ID's that are still in the database (copy&paste within the same file).
-- fallback to name lookup.
-- fallback to loading them from the original filepath (movie-clip and sound only).
also fix bug pasting where initialing the sound wasn't done if there was no frame-offset.

- BKE_mask_update_scene was only used with do_newframe=FALSE,
removed this argument.
- Made it so BKE_mask_update_scene is able to handle LIB_ID_RECALC_DATA
case. Namely, if mask ID is tagged for data update it means shapekeys
will be re-evaluated (as if do_newframe=true).
If mask id only tagged for LIB_ID_RECALC, then no shapekey evaluation
happens (same as it used to behave before).
This means, doing DAG_id_tag_update(&mask->id, OB_RECALC_DATA) will
lead to shapekeys re-evaluation which is really needed in such
operators as clearing shapekeys (and cleaning shapekeys which is
in tomato branch yet).
This is a bit silly to use OB_RECALC_DATA sine mask is not an OB,
but could not see better way to do it now.
This fixes missing mask re-evaluation after clearing shapekey,
would expect no other functional changes.

- Added MaskLayer.splines.new (which creates single spline
and returns pointer to it).
- Added MaskLayer.splines.remove() to remove given spline.
- Added MaskSpline.points.new() which creates new point
in the origin and returns pointer to it.
- Added MaskSpline.points.remove() to remove given point.

Also done a few cleanup here and there...

PyNodes opens up the node system in Blender to scripters and adds a number of UI-level improvements.
=== Dynamic node type registration ===
Node types can now be added at runtime, using the RNA registration mechanism from python. This enables addons such as render engines to create a complete user interface with nodes.
Examples of how such nodes can be defined can be found in my personal wiki docs atm [1] and as a script template in release/scripts/templates_py/custom_nodes.py [2].
=== Node group improvements ===
Each node editor now has a tree history of edited node groups, which allows opening and editing nested node groups. The node editor also supports pinning now, so that different spaces can be used to edit different node groups simultaneously. For more ramblings and rationale see (really old) blog post on code.blender.org [3].
The interface of node groups has been overhauled. Sockets of a node group are no longer displayed in columns on either side, but instead special input/output nodes are used to mirror group sockets inside a node tree. This solves the problem of long node lines in groups and allows more adaptable node layout. Internal sockets can be exposed from a group by either connecting to the extension sockets in input/output nodes (shown as empty circle) or by adding sockets from the node property bar in the "Interface" panel. Further details such as the socket name can also be changed there.

Issue happened for scene. movie clip and mask strips, which contains
pointers to datablocks which are freeing on loading new file.
Also, scene strip would crash when pasted from clipboard after scene
was unlinked from file.
|
|
Issue was caused by couple of circumstances:
- Normal Map node requires tesselated faces to compute tangent space
- All temporary meshes needed for Cycles export were adding to G.main
- Undo pushes would temporary set meshes tessfaces to NULL
- Moving node will cause undo push and tree re-evaluate fr preview
All this leads to threading conflict between preview render and undo
system.
Solved it in way that all temporary meshes are adding to that exact
Main which was passed to Cycles via BlendData. This required couple
of mechanic changes like adding extra parameter to *_add() functions
and adding some *_ex() functions to make it possible RNA adds objects
to Main passed to new() RNA function.
This was tricky to pass Main to RNA function and IMO that's not so
nice to pass main to function, so ended up with such decision:
- Object.to_mesh() will add temp mesh to G.main
- Added Main.meshes.new_from_object() which does the same as to_mesh,
but adds temporary mesh to specified Main.
So now all temporary meshes needed for preview render would be added
to preview_main which does not conflict with undo pushes.
Viewport render shall not be an issue because object sync happens from
main thread in this case.
It could be some issues with final render, but that's not so much
likely to happen, so shall be fine.
Thanks to Brecht for review!

crash caused by own commit r50969, the fix exposed a crash in an area of code that must have never been used before.

- movieclip unlink didn't clear node ID pointers from the scene (leaving dangling pointers).
- mask datablock unlink was clearning references from scene nodes twice.

C with gcc.
helps for finding unused functions and making functions static, also did some minor code cleanup.
|
|
- freeing a mask from RNA BKE_libblock_free() twice on the mask.
- loading a new blend file would only free the mask and not unlink it from nodes - it would access freed memory.

[Even | Smooth]
- Even preserves thickness but can give unsightly loops
- Smooth gives nicer shape but can give unsightly feather/spline mismatch for 'S' shapes created by beziers.
This is an example where smooth works much nicer.
