Better to make internal code naming match official/UI naming to some
extent, this will reduce confusion in the future.
This is 'breaking' scripts and files that would use that feature, but
since it is not yet officially supported nor exposed in 2.80, as far
as that release is concerned, it is effectively
a 'no functional changes' commit.
- Move connected & projected into individual toggles.
- Top-level proportional editing button now only toggles.
- Use popover for proportional edit-mode falloff and options.
Note that it's no longer possible to toggle connected via key bindings,
although this could be supported again if it's needed.
Resolves T58081
BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.
See P901 for script to perform these edits.
Some features are incompatible with multithreading and reliable evaluation
of dependencies. We are now removing them as part of a bigger cleanup to
fix bugs in keyframing and invalid animation evaluations.
* Dupliframes have been removed. This was a hack added before there were
more powerful features like the array modifier.
* Slow parent has been removed, never worked in 2.8. It was always
unreliable for use in production due to depending on whatever frame was
previously evaluated, which was not always the previous frame.
* Particle instanced objects used to have their transform evaluated at
the particle time. Now it always gets the current time transform.
* Boids can no longer do predictive avoidance of force field objects,
but still for other particles.

This should be purely an implementation change,
for end users there should be no functional difference.
The entire key configuration is in one file with ~5000 lines of code.
Mostly avoiding code duplication and preserve comments and utility
functions from the C code.
It's a bit long but for searching and editing it's also convenient to
have it all in one file.
Notes:
- Actual keymap is shared by blender / blender_legacy
and stored in `keymap_data/blender_default.py`
This only generates JSON-like data to be passed into
`keyconfig_import_from_data`, allowing other presets to load and
manipulate the default keymap.
- Each preset defines 'keyconfig_data'
which can be shared between presets.
- Some of the utility functions for generating keymap items still
need to be ported over to Python.
- Some keymap items can be made into loops (marked as TODO).

* Proportional pie menu at shift+O.
* Snap pie menu at shift+S.
* Pivot pie menu at comma. Previous comma, ctrl+comma, period
and ctrl+period shortcuts for specific pivot types were removed.
Ref T56881.
Add tool options to control how select operates (add/sub/set/and/xor).
Note: edit mode armature select still needs to support all options,
this is complicated by how it handles partial end-point selection.

This is the result of nearly two years of development and I want thanks firstly the other members of the grease pencil team: Daniel M. Lara, Matias Mendiola and Joshua Leung for their support, ideas and to keep working in the project all the time, without them this project had been impossible.
Also, I want thanks other Blender developers for their help, advices and to be there always to help me, and specially to Clément Foucault, Dalai Felinto, Pablo Vázquez and Campbell Barton.
Based on discussion with @eyecandy & @venomgfx,
we agreed that Tab drag/click, is too easy to accidentally press
while moving the cursor.
It's also not typical to activate the operator on release which
introduces a small lag switching edit-mode.
This is a shame since in some ways its a nice way to re-use the key,
overall it just feels a little too unpredictable for such an important
action.
This commit makes the following changes.
- Tab: toggles edit-mode.
- Ctrl-Tab: opens pie menu.
- Ctrl-AccentGrave: toggles manipulator.
Note, while AccentGrave isn't always available
this shortcut is not essential.
In the outliner there are now icons for it, Ctrl+Click isolates a
single collections.
In the 3D view, Ctrl+H key opens a menu that is more or less the
equivalent of the old layer buttons in the header. Regular Click isolates
the collection, Shift+Click toggle the collection visibility. Pressing
number keys and letters works in this menu, which can help for quickly
selecting a specific collection.
Shortcuts for quick switching by just pressing 1/2/3/.. keys are available
again. The order can be confusing with nested collections, but that seems
unavoidable. The first numbers control the top level collections, and then
sub collections if numbers are left.
Remaining design issues:
* The 3D view menu needs to be improved: support for sub collections,
staying open on shift+click, access from the 3D view header somewhere,
shortcut key display.
* Currently collection hiding just controls per-object hiding, we plan
to separate this state still so alt+H doesn't affect collection hiding.
H hides selected objects, Shift+H hides unselected objects, and Alt+H
reveals hidden objects.
This hiding state is distinct from restrict viewport and render, and
meant for temporarily hiding objects without affecting more persistent
collection hiding.
Object hiding is per view-layer, same as selection. It affects the
viewport and any preview renders in there, but not final renders.
In the outliner, different icons are now used for temporary hiding, and
restrict viewport and render. Hidden objects are greyed out.
Remaining design issues:
* For lamps we probably still want to keep their effect on the scene,
currently they are fully disabled by hiding. Arguably mesh lights or
even objects being reflected or casting shadows are not that different
but perhaps the special lamp exception from local view should remain.
* We need a feature still to disabled this hiding for specific viewports,
for render or animation preview where you want to see the entire scene
while working in another view.
* We need a new icon for restrict viewport, for now it uses a grid similar
to the 2.4 icon.
* Hiding objects does not preserve selection state as it did in 2.7,
it's probably convenient to support this again?
After testing in the studio and extending the event system for
drag events, we've agreed on adjustments to the new keymap,
see: T55162
- Tab: Edit-mode toggle.
- Tab + Cursor Drag: mode switching pie menu.
- Accent/Grave: for 3D view pie menu.
- F3: Search
- 1..3, Shift-1..3: Edit mesh vertex/edge/face toggle.
Other minor changes were made, however they aren't part of the design.
- Ctrl-Shift-S: Image editor Save-As (was F3)
- Ctrl-Alt-R: Repeat history (was F3)
Use the same key for pose & weight paint mode (instead of texture paint)
This makes more sense since pose/weight paint modes
are often used in combination.
- Use Tab key for search.
- Number keys switch modes.
- The number of the current mode can open a submode menu
(currently only works for edit-mode)
- Ctrl-Tab, Ctrl-Shift-Tab - cycle workspaces.
OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

Folders removed entirely:
* //extern/recastnavigation
* //intern/decklink
* //intern/moto
* //source/blender/editors/space_logic
* //source/blenderplayer
* //source/gameengine
This includes DNA data and any reference to the BGE code in Blender itself.
We are bumping the subversion.
Pending tasks:
* Tile/clamp code in image editor draw code.
* Viewport drawing code (so much of this will go away because of BI removal
that we can wait until then to remove this.
Use Shift+G > Collection. If there is only one collection, it just selects it,
if there are multiple ones user get to pick which one to select.
This is the same behaviour we have for groups. Note, we only select objects
directly in the collection, not the ones in any nested collection.
Feature suggested by Pablo Vazquez (venomgfx)
How to use: Select a few objects, and press "M" in the viewport.
If you hold ctrl the objects will be added to the selected collection.
Otherwise they are removed from all their original collections and moved
to the selected one instead.
Development Notes
=================
The ideal solution would be to implement an elegant generic multi-level
menu system similar to toolbox_generic() in 2.49.
Instead I used `uiItemMenuF` to acchieve the required nesting of the menus.
The downside is that `uiItemMenuF` requires the data its callback uses to be
always valid until the menu is discarded. But since there is no callback we
can call when the menu is discarded for operators that exited with
`OPERATOR_INTERFACE`.
That means we are using static allocated data, that is only freed next time
the operator is called. Which also means there will always be some
memory leakage.
