This option makes an operator to not push a task to the undo stack if the previous stored elemen is the same operator or part of the same undo group.
The main usage is for animation, so you can change frames to inspect the
poses, and revert the previous pose without having to roll back tons of
"change frame" operator, or even see the undo stack full.
This complements rB13ee9b8e

Previously the pose library used the WholeCharacter key set, which ignores
selection and add keys for almost all bones in the rig. This is a very
slow operation on complex rigs. With this patch, only selected bones are
keyed, defaulting to keying all bones when none are selected.
Note that this fixes the FIXME previously mentioned in the source.
Drawing used colors for select (TH_EDGE_SELECT/TH_VERTEX_SELECT) which was inconsistent with crease, seam, sharp, .. (which all had their own them color -- also was a bit hard to read).
NOTE: UI team usually doesn't allow adding more theme options, this is an exception.

Uses similar way of storing temp data as object copy paste, just
uses different read entrypoint which does not modify current bmain.
This gives ability to easily copy-paste poses from one blender to
another one.
Hopefully doesn't introduce user-measurable differences.

The idea is to allow certain animation channels to be always visible in
animation editors. So, for example, one can pin Camera animation to the
editor so it is always possible to refine/tweak camera animation when
animating something else in the scene.
There is probably some more polishing required, and some current
limitations could be solved in the future but should be a good starting
point already.
Currently only works for object without recursing into deeper datablock
(so for example, it's not possible to pin object material animation).

Now the factor works similar to other Blender areas to make the factor
more consistent for artists. The value 0% means equal to original
stroke, 100% equal to final stroke (50% means half way). Any value below
0% or greater than 100% create an overshoot of the stroke.
Two new modal operators to create a grease pencil interpolate drawing
for one frame or a complete sequence between two frames. For drawing
the temporary strokes in the viewport, two drawing handlers have been
added to manage 3D and 2D stuff.
Video: https://youtu.be/qxYwO5sSg5Y
The operator shortcuts are Ctrl+E and Ctrl+Shift+E. During the modal
operator, the interpolation can be adjusted using the mouse (moving
left/right) or the wheel mouse.
In User Preferences, Properties Editor and toolshelf, Ctrl+Tab and Ctrl+Shift+Tab now activates the next or previous space context (or category in case of toolshelf tabs), respectively.
For Properties Editor such functionality was completely missing, only toolshelf allowed cycling using ctrl+mousewheel (or only mousewheel while hovering tab region). Ctrl+Tab and Ctrl+Shift+Tab are common web browser shortcuts, so they're a reasonable choice to go with.
Reaching the first/last item doesn't cause the cycling to stop, we continue at the other end of the list then. (I didn't add this to Ctrl+Mousewheel toggling in toolshelf since I wanted to keep its behavior unchanged.)
We could get rid of (Ctrl+)Mousewheel cycling in toolshelf, but this may break user habits.
The cycling happens using a new operator, UI_OT_space_context_cycle, for toolshelf tabs it's hardcoded in panel handling code though.
Generalized rna_property_enum_step a bit and moved it to rna_access.c to allow external reuse.

Issue was that the wm.open_mainfile OP caused all handlers to be removed and since rB45592291 cancelled (which is correct in general), the menu that triggered the OP should not be cancelled though.
Not sure if this is a nice fix or not, it's however the safest fix I found. A different fix would be to call UI_popup_block_close before WM_operator_call_ex (in dialog_exec_cb), but not sure how safe this is and want to further investigate if it makes other hacks/fixes redundant.
There's still a crash with --debug-memory that confused the heck out of me (since I always have --debug-memory enabled), but I'll commit fix for that separately.
All in all, this patch adds an Alembic importer, an Alembic exporter,
and a new CacheFile data block which, for now, wraps around an Alembic
archive. This data block is made available through a new modifier ("Mesh
Sequence Cache") as well as a new constraint ("Transform Cache") to
somewhat properly support respectively geometric and transformation data
streaming from alembic caches.
A more in-depth documentation is to be found on the wiki, as well as a
guide to compile alembic: https://wiki.blender.org/index.php/

Report popups simply reuse popup menu code, so their blocks got "UI_popup_menu_begin" assigned as name, which was a bit misleading. Now uses "UI_popup_menu_reports".
Ideally they'd have their own popup code.
The snapping functions when performed in the perspective view,
have some problems in the threshold (a distortion) and in the clip plane (the normal is incorrect).
These problems can be only observed when making the snap to edges or to vertices (nearest to ray function).
This patch propose a totally different solution.
The idea is to project the edges of bvh nodes and test the 2d projection of the snap element.
For this it used the BLI_bvhtree_walk_dfs function.
It is important to pay particular attention also to the changes in `ED_transform_snap_object_project_view3d_ex`
Currently "long keyframes" are only useful for indicating where stationary
holds occur. If however you try to create a "moving hold" (where the values
are slightly different, but in terms of overall effect, it's still a hold)
then it could get tricky to keep track of where these occur.
Now it's possible to tag such keyframes (using the keyframe types - RKEY)
as being part of a moving hold. These will not only be drawn differently
from normal keyframes, but they will also result in a "long keyframe"
being drawn between each pair of them, just like if they had been completely
stationary instead.
Currently the theming/styling of these is a bit rough. They reuse the existing
theme colours for long keyframes.
This commit introduces a scale factor setting for scaling all keyframe indicators
in the Dopesheet Editor up/down, in order to make them easier to select. It is perhaps
most useful for keyframe types which are usually indicated using smaller keyframes
(e.g. breakdown), which may get tricky to quickly select.
Problem was in fact slightly wider, File space was nearly not taking into account
library navigation case and its 'virtual' directoris, except in a few places.
Add a wrapper around BLI_is_dir that also check for lib paths, and used it in
ED_file_change_dir(), such that we now always check path is a
valid directory - in the filebrowser context, not filesytem context. ;)
To get this working the least effort, I've had to expose the helper functions
used by the lasso and circle select keyframe-test callbacks (which are generic)
and expose them for use by the GP keyframe editing code too. Hopefully in time
we clean this all up and just write the code once to operate on "keyframes"
This only works in the Action and Dopesheet modes (which operate on FCurve keyframes).
Support for Grease Pencil and Mask Keyframes though is still pending.
This commit changes a lot of how IDs are handled internally, especially the unlinking/freeing
processes. So far, this was very fuzy, to summarize cleanly deleting or replacing a datablock
was pretty much impossible, except for a few special cases.
Also, unlinking was handled by each datatype, in a rather messy and prone-to-errors way (quite
a few ID usages were missed or wrongly handled that way).
One of the main goal of id-remap branch was to cleanup this, and fatorize ID links handling
by using library_query utils to allow generic handling of those, which is now the case
(now, generic ID links handling is only "knwon" from readfile.c and library_query.c).
This commit also adds backends to allow live replacement and deletion of datablocks in Blender
(so-called 'remapping' process, where we replace all usages of a given ID pointer by a new one,
or NULL one in case of unlinking).
This will allow nice new features, like ability to easily reload or relocate libraries, real immediate
deletion of datablocks in blender, replacement of one datablock by another, etc.
Some of those are for next commits.
A word of warning: this commit is highly risky, because it affects potentially a lot in Blender core.
Though it was tested rather deeply, being totally impossible to check all possible ID usage cases,
it's likely there are some remaining issues and bugs in new code... Please report them! ;)

Being granular means we need to re-build depsgraph a bit more often..
The issue was caused by rigidbody requiring some special nodes to
handle physics which were not created with just tagging object for
update.
This covers the following workflow. Animator will disable Update All 3D views
in order to get quick playback in a particular 3D editor. However, it also
handy to see playback in all editors and image editors to see comparison of
animation and reference footage.
So the idea here is to refresh reasonable editors when playback is invoked
from animation editors.

- the parameter `snap_to_flag` was moved to outside `SnapObjectParams`.

This commit/patch/branch brings a bunch of powerful new options for B-Bones and
for working with B-Bones, making it easier for animators to create their own
rigs, using fewer bones (which also means hopefully lighter + faster rigs ;)
This functionality was first demoed by Daniel at BConf15
Some highlights from this patch include:
* You can now directly control the shape of B-Bones using a series of properties
instead of being restricted to trying to indirectly control them through the
neighbouring bones. See the "Bendy Bones" panel...
* B-Bones can be shaped in EditMode to define a "curved rest pose" for the bone.
This is useful for things like eyebrows and mouths/eyelids
* You can now make B-Bones use custom bones as their reference bone handles,
instead of only using the parent/child bones. To do so, enable the
"Use Custom Reference Handles" toggle. If none are specified, then the BBone will
only use the Bendy Bone properties.
* Constraints Head/Tail option can now slide along the B-Bone shape, instead of
just linearly interpolating between the endpoints of the bone.

Take advantage of the efficiency provided by the snap_context.
Also fixes errors:
- volume snap fails based on view angle (T48394).
- multiple instances of dupli-objects break volume calculation.
This commit avoids draw of invisible parts of image in image editor,

Especially handy when painting on a high-res image when zoomed-in.
Separate the creation of trees from EditMesh from the creation of trees from DerivedMesh.
This was meant to simplify the API, but didn't work out so well.
`bvhtree_from_mesh_*` actually is working as `bvhtree_from_derivedmesh_*`.
This is inconsistent with the trees created from EditMesh. Since for create them does not use the DerivedMesh.
In such cases the dm is being used only to cache the tree in the struct DerivedMesh. What is immediately released once
bvhtree is being used in functions that change(tag) the DM cleaning the cache.
- Use a filter function so users of SnapObjectContext can define how edit-mesh elements are handled.
- Remove em_evil.
- bvhtree of EditMesh is now really cached in the snap functions.
- Code becomes organized and easier to maintain.
This is an important patch for future improvements in snapping functions.
Now CD_SHAPEKEY_INDEX customdata is stored in edit-mode when hooks and vertex parents are used.
This also fixes a bug where undo would loose key-index data.
Move to structs for BM_mesh_bm_to/from_me to avoid passing many argument, which mostly aren't used.
This introduces a snap-context that can be re-used for casting rays into the scene
(by operators such as walk-mode, ruler and transform code).
This can be used to cache data between calls too.
Cursor is now set to standard arrow-cursor when opening menu, and reset to previous one when closing it. Previously it just stayed as it was before, e.g. the edit mode cross-cursor stayed active even if a menu was opened.
Fixes T48192.
This was a feature request from a few years back (IIRC from ZanQdo?) to make it
easier to reuse one set of driver variables across several different drivers.
Dev Notes:
* Finally it's done! All that trouble for two little buttons.
* Grr... cmake... grrr!
* This includes the "manually create" modes, which correspond to the previous behaviour
for setting up drivers. This is necessary when the current screen layout is not
well suited to having multiple property editors open (e.g. small screen or heavily
subdivided screen).
* Only the modes relevant for the current property type (i.e. array vs single)
will be shown
* The "Add Driver" entries in the RMB context menu have now been replaced by a
submenu which will list all the available mapping types.
* NOTE: The code for the ANIM_OT_button_driver_add() operator is perhaps a bit hairy.
However, it currently allows us to have the desired behaviour. It can always get
cleaned up later though.
Although it isn't currently exposed, this allows for the old behaviour,
where an "empty" driver was added (without any target assigned yet).
For this reason, it's also referred to as the "Manual" mode.
There are also some attempts at improving the tooltips + names for the
other modes (again, not shown anywhere yet)
This commit brings some long requested improvements to the workflow for setting up
drivers, which should make it easier and faster to set up new drivers in a more
interactive fashion.
The new workflow is as follows:
1) Hover over the property (e.g. "Lamp Energy" or "Y Location") or properties ("Rotation")
you wish to add drivers to. We'll refer to this as the "destination"
2) Ctrl-D to active the new "Add Drivers" eyedropper
3) Click on the property you want to use as the source/target. The property under the
mouse will be used to drive the property you invoked Ctrl-D on.
For example, to drive the X, Y, and Z location of the Cube using the Y Location of the Lamp,
hover over any of the X/Y/Z location buttons, hit Ctrl-D, then click on the Y-Location
button of the Lamp object. Drivers will be added to the X, Y, and Z Location properties
of the Cube; each driver will have a single variable, which uses the Y-Location Transform
Channel of the Lamp.
Tips:
- Transform properties will automatically create "Transform Channel" driver variables.
Everything else will use "Single Property" ones
- Due to the way that Blender's UI Context works, you'll need two Properties Panel instances
open (and to have pinned one of the two to show the properties for the unselected
object). It's slightly clunky, but necessary for implementing a workflow like this,
as the UI cannot be manipulated while using eyedroppers to pick data.
- The eyedropper operator implemented here actually has three modes of operation.
1) The "1-N" (one to many) mode is the default used for Ctrl-D, and "Add Driver to All"
in the RMB Menu. This is the behaviour described above.
2) There's also a "1-1" (one to one) mode that is used for the "Add Single Driver" in the
RMB Menu.
3) Finally, there's the "N-N" mode (many to many), which isn't currently exposed.
The point of this is to allow mapping XYZ to XYZ elementwise (i.e. direct copying)
which is useful for things like locations, rotations, scaling, and colours.
Implementation Notes:
- The bulk of the driver adding logic is in editors/animation/drivers.c, where most of
the Driver UI operators and tools are defined
- The property eyedropper code is in interface_eyedropper.c along with all the other
eyedroppers (even though they don't share much actual code in common). However, this
turns out to be necessary, as we can't get access to many of the low-level buttons API's
otherwise.
Todo:
- It may be necessary to restore a way to access the old behaviour (i.e. "manual setup")
in case it is not practical to immediately pick a property.
- Other things to investigate here include extra hotkeys (e.g. Ctrl-Shift-D for Add Single?),
and to expose the N-N mode.
- Other things we could try include interactively applying scaling factors, picking
multiple targets (e.g. for location difference and rotation difference drivers),
and/or other ways of using these property picking methods.
