Now it is forumlated in terms of deltas, and consists of the
following steps:
- Original displacement at the reshape level are being backed up.
- New displacement is being written by the reshape routines.
- Delta of the displacement is calculated.
- Deltas are propagated to the higher levels, which also includes
their interpolation/
- Original displacement is restored.
- New interpolated displacements are added to the original ones.
This is a base ground for the upcoming change related on using
Catmull-Clark smoothing for the deltas instead of linear
interpolation. Currently is no changes for artists, just preparing
for upcoming work.
The main use one can imagine for this is adding tweak controls to
parts of a model that are already deformed by multiple other major
bones. It is natural to expect such locations to deform as if the
tweaks aren't there by default; however currently there is no easy
way to make a bone follow multiple other bones.
This adds a new constraint that implements the math behind the Armature
modifier, with support for explicit weights, bone envelopes, and dual
quaternion blending. It can also access bones from multiple armatures
at the same time (mainly because it's easier to code it that way.)
This also fixes dquat_to_mat4, which wasn't used anywhere before.

- Vertex & weight paint now use the 'blend' setting.
- Weight paint now has it's own tool setting,
since weight paint doesn't deal with color - we'll likely
support different tools eventually.
Previously the brush names were used which had the limit that:
- Brush names that were deleted wouldn't show up in the toolbar.
- Naming collisions between user defined brushes and existing tools
broke tool selection.
Now brushes are created as needed when tools are selected.
Note, vertex/weight paint combine tool and blend modes,
this should be split out into a separate enum.
When you check for undone work before acquiring a lock that ensures you
are the only one actually doing the work, you have to redo the check
*after* acquiring said lock.
Otherwise, there is room for nasty random race condition issues...
If the user only needs insertion and removal from top, there is
no need to allocate and manage separate HeapNode objects: the
data can be stored directly in the main tree array.
This measured a 24% FPS increase on a ~50% heap-heavy workload.

It was getting too impractical to call BKE_paint_brush_tool_info
which needed to lookup the scene pointers.
Now each store tool offset and brush mode in 'Paint.runtime'
Each mode had its own logic for initializing paint structs,
move to a single function.
Also remove "BKE_brush_get_gpencil_paint", entering grease pencil
mode is responsible for ensuring the data is created.
Now the grid is always controlled by the topbar selector and not in the canvas panel. To have two places to define orientation was confuse.
The orientation by default (no lock) is always to view plane.
This is sued by both object joinig and object apply scale operations.
Currently only uniform scale is working correct. Non-uniform gets averaged
and will produce slightly distorted results. This is something we should
fix, but priority of this particular case is not so high.
We want to undo the initial usercount from low-level ID duplication, not
to erase all possible extra processing (like e.g. setting Fake User...).
Fixes part of mess in brush usercount.
First of all, follow our naming convention to use module prefix.
Second of all, mesh is being created and is to be freed, we also
have convention for such function names.
This only works thing around, just so we can unlock production here.
Joining objects of a different scale will not yet work correctly.
Proper fix is coming later (the code needs to be ported to new
Subdiv API).
The toolbar now shows brush types, the brush selector now
only shows brushes matching the current tool type.
Details:
- Add's Paint.tool_slots (used by the toolbar).
- Removed custom grease pencil brush tool code.
- Bumped subversion.
See T57526 for details.
This option make the internal render size larger than the output size in
order to minimize screenspace effects disapearing at the render edges.
The overscan size added around the render is the maximum dimension
multiplied by the overscan percentage.
@jpbouza was rather upset these were made read-only, and unlike
parents, it's not that hard to allow changing these Bone fields:
all is needed is to carefully refresh the matching fields in the
relevant bPoseChannel objects and properly tag update.

Only affects internal API, bout could be exposed as an option for
the compatibility reasons with other software.
Is a part of some ongoing development of multires, but might or
might not be used.
Support for showing images in background/foreground and only in perspective/orthographic view.
Internally the depth of the image is modified in the fragment shader by setting `gl_FragDepth` explicitly.
The UI still needs some work to improve usability, see D3863 for details.
Currently there is one duplicated function, not sure how to best deduplicate it yet. (`is_image_empty_visible`)

Also reshuffle a bit that whole code, did some renaming,
`BKE_id_to_unique_string_key()` is now using same base code (instead of
using whole library filepath...), etc.
When enabled, inserting keyframes into F-Curves with simple cyclic
extrapolation (the same conditions as required for cycle-aware auto
handle smoothing to activate) will take the cycle into account:
- Keyframes that are being inserted outside of the cycle bounds
are remapped to be inside the cycle. Thus it is not necessary
to be within the main iteration of the cycle when tweaking.
This becomes especially useful in the final animation tweaking
phase when the channel keys may be staggered for overlap, so
the actual master period is different for different channels.
- Modifying one of the end points of a cycle also changes the
other end point when appropriate, to preserve smooth transition.
This feature applies to both manual keyframe insertion using
'I', and auto-keyframing.

This will probably be a temporary solution to fill empty space, for until we
have a search button there. Hence, I made this optional using a compile flag.
Moves the Properties editor context switching to a vertical tabs region.
Design Task: T54951
Differential Revison: D3840
The tabs are regular widgets, unlike the 'old' toolshelf tabs. This means they
give mouse hover feedback, have tooltips, support the right-click menu, etc.
Also, when vertical screen space gets tight, the tabs can be scrolled, they
don't shrink like the toolshelf ones.
The tab region is slightly larger than the header. The tabs are scaled up
accordingly. This makes them nicely readable.
The header is quite empty now. As shown in T54951, we wanted to have a search
button there. This should be added next.
Implementation Notes:
* Added a new region type, RGN_TYPE_NAVIGATION.
* Having the tabs in a separate region allows scrolling of the tab-bar, unlike
the toolshelf tabs. We might want to remove the scrollbars though.
* Added a new region flag RGN_FLAG_PREFSIZE_OR_HIDDEN, to ensure the tab region
is either hidden or has a fixed size.
* Added some additional flags to support fine-tuning the layout in panel and
layout code.
* Bumps subversion.
With the new automatic handle algorithm, it is possible to do a lot
of the animation via keyframes without touching the curves. It is
however necessary to change the keyframe interpolation and handle
types in certain cases. Currently the dopesheet/action editor
allows changing the types, but does not show them in any way.
To fix, add a new menu option to display this information. For handle
type, it is represented using the shape of the key icons: diamond for
Free, clipped diamond for Aligned, square for Vector, circle for Auto
Clamp, and cirle with dot for Automatic.
Non-bezier interpolation is a property of intervals between keys,
so it is marked by drawing lines, similar to holds. In this initial
version, only the fact of non-bezier interpolation is displayed,
without distinguishing types. For summaries, the line is drawn at
half alpha if not all curves in the group are non-bezier.
In addition, it is sometimes helpful to know the general direction
of change of the curve, and which keys are extremes. This commit
also adds an option to highlight extremes, based on comparing the
keyed values with adjacent keys. Half-intensity display is used
for overshot bezier extremes, or non-uniform summaries.
