* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.

This reverts commit 5aa19be912 and b4a721af69.
Due to postponement of particle system rewrite it was decided to put particle code
back into the 2.8 branch for the time being.
WARNING! Full build is broken, alembic has not been merged in correctly and has some references to particle stuff.
Don't have time to tackle this now (and probably would be better if someone knowing what he's doing does it anyway).

Using context.active_gpencil_brush to access the active Grease Pencil brush
would result in a crash if trying to rename the brush, because the "ID" pointer
was not set.
To be backported to 2.78
* Added a new API function to test if a GPencil layer is visible or not
* Replaced all editability checks with this new "super check"
* Replaced all magic number thresholds for opacity visiblity with a single define
This resolves a problem where selected items edited for multi-value-editig
could include objects not in any visible views (unlocked layers, local view... etc).
The problem here was that when a Grease Pencil datablock is shared between
the 3D view and another one of the editors, all the strokes were getting handled
by the editing operators, even if those strokes could not be displayed/used
in that context. As a result, the coordinate conversion methods would fail,
as some of the needed data would not be set.
The fix here involves not including any offending strokes in such cases...
This merge-commit brings in a number of new features and workflow/UI improvements for
working with Grease Pencil. While these were originally targetted at improving
the workflow for creating 3D storyboards in Blender using the Grease Pencil,
many of these changes should also prove useful in other workflows too.
The main highlights here are:
1) It is now possible to edit Grease Pencil strokes
- Use D Tab, or toggle the "Enable Editing" toggles in the Toolbar/Properties regions
to enter "Stroke Edit Mode". In this mode, many common editing tools will
operate on Grease Pencil stroke points instead.
- Tools implemented include Select, Select All/Border/Circle/Linked/More/Less,
Grab, Rotate, Scale, Bend, Shear, To Sphere, Mirror, Duplicate, Delete.
- Proportional Editing works when using the transform tools
2) Grease Pencil stroke settings can now be animated
NOTE: Currently drivers don't work, but if time allows, this may still be
added before the release.
3) Strokes can be drawn with "filled" interiors, using a separate set of
colour/opacity settings to the ones used for the lines themselves.
This makes use of OpenGL filled polys, which has the limitation of only
being able to fill convex shapes. Some artifacts may be visible on concave
shapes (e.g. pacman's mouth will be overdrawn)
4) "Volumetric Strokes" - An alternative drawing technique for stroke drawing
has been added which draws strokes as a series of screen-aligned discs.
While this was originally a partial experimental technique at getting better
quality 3D lines, the effects possible using this technique were interesting
enough to warrant making this a dedicated feature. Best results when partial
opacity and large stroke widths are used.
5) Improved Onion Skinning Support
- Different colours can be selected for the before/after ghosts. To do so,
enable the "colour wheel" toggle beside the Onion Skinning toggle, and set
the colours accordingly.
- Different numbers of ghosts can be shown before/after the current frame
6) Grease Pencil datablocks are now attached to the scene by default instead of
the active object.
- For a long time, the object-attachment has proved to be quite problematic
for users to keep track of. Now that this is done at scene level, it is
easier for most users to use.
- An exception for old files (and for any addons which may benefit from object
attachment instead), is that if the active object has a Grease Pencil datablock,
that will be used instead.
- It is not currently possible to choose object-attachment from the UI, but
it is simple to do this from the console instead, by doing:
context.active_object.grease_pencil = bpy.data.grease_pencil["blah"]
7) Various UI Cleanups
- The layers UI has been cleaned up to use a list instead of the nested-panels
design. Apart from saving space, this is also much nicer to look at now.
- The UI code is now all defined in Python. To support this, it has been necessary
to add some new context properties to make it easier to access these settings.
e.g. "gpencil_data" for the datablock
"active_gpencil_layer" and "active_gpencil_frame" for active data,
"editable_gpencil_strokes" for the strokes that can be edited
- The "stroke placement/alignment" settings (previously "Drawing Settings" at the
bottom of the Grease Pencil panel in the Properties Region) is now located in
the toolbar. These were more toolsettings than properties for how GPencil got drawn.
- "Use Sketching Sessions" has been renamed "Continuous Drawing", as per a
suggestion for an earlier discussion on developer.blender.org
- By default, the painting operator will wait for a mouse button to be pressed
before it starts creating the stroke. This is to make it easier to include
this operator in various toolbars/menus/etc. To get it immediately starting
(as when you hold down DKEy to draw), set "wait_for_input" to False.
- GPencil Layers can be rearranged in the "Grease Pencil" mode of the Action Editor
- Toolbar panels have been added to all the other editors which support these.
8) Pie menus for quick-access to tools
A set of experimental pie menus has been included for quick access to many
tools and settings. It is not necessary to use these to get things done,
but they have been designed to help make certain common tasks easier.
- Ctrl-D = The main pie menu. Reveals tools in a context sensitive and
spatially stable manner.
- D Q = "Quick Settings" pie. This allows quick access to the active
layer's settings. Notably, colours, thickness, and turning
onion skinning on/off.
Make the UI API more consistent and reduce confusion with some naming.
mainly:
- API function calls
- enum values
some internal static functions have been left for now
... instead add scene.sequencer_editor_create / clear, these match id.animation_data_* functions.
- refactor for names, for scene level functions call them BKE_sequencer_*
ended up having to add a new pointer into the uiBlock (which I'd rather have avoided), but setting the uiLayoutSetContextPointer(..) was complicated to properly use for submenus and popus.
to enable from python:
bl_options = {'REGISTER', 'UNDO', 'PRESET'}
from C:
ot->flag= OPTYPE_REGISTER|OPTYPE_UNDO|OPTYPE_PRESET;
- added context member 'active_operator'
- enable this for 'Add Torus' for testing.
- active is no longer assumed to be selected.
this fixes a simple bug - eg: Adding a new armature, entering pose mode and toggling selection failed.
- outliner editbone selection now works like object and pose mode.
- mouse selection sets the bone active even when the tip is selected.
- active, unselected bones draw as wire color with a 15% tint of the selected color.
Added extend option to lasso.
also...
- selecting bones wasn't checking their layer of if they were hidden in a number of places.
- fixed memory leak.
small unrealed changes
- added PBONE_VISIBLE macro
- renamed functions used for paint selectoin from *_tface to paintface_*. sine they no longer have anything todo with tface's.
- removed scanfill include from BLI_blenlib.h, this is only used in very few places and quite specific.
Noticed lasso select is broken for metaballs and face mask mode but this has been the case for a while, will look into it next.
Only source/blender/editors/ dir, should not give errors on different platforms
Only removing: UI_*.h, ED_*.h, WM_*.h, DNA_*.h, IMB_*.h, RNA_*.h, PIL_*.h
