Before, the operators only worked in the current frame

Before, the weight data array was created always, but now only is added when a weight value is assigned.
This change was suggested by algorithm, and both agreed it was good idea.

This commit merge the full development done in greasepencil-object branch and include mainly the following features.
- New grease pencil object.
- New drawing engine.
- New grease pencil modes Draw/Sculpt/Edit and Weight Paint.
- New brushes for grease pencil.
- New modifiers for grease pencil.
- New shaders FX.
- New material system (replace old palettes and colors).
- Split of annotations (old grease pencil) and new grease pencil object.
- UI adapted to blender 2.8.

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.

Sometimes one needs a *lot* of changes for a single G.main... :/

'graph' is waaaayyyyy too generic name outside of DEG context, and
better try to use same name everywhere!
|
|
Currently set when setting the cursor location,
optionally used as an orientation type.
Intended for use by tools too.
See: D3208

The depsgraph was always created within a fixed evaluation context. Passing
both risks the depsgraph and evaluation context not matching, and it
complicates the Python API where we'd have to expose both which is not so
easy to understand.
This also removes the global evaluation context in main, which assumed there
to be a single active scene and view layer.

Both object level and camera datablock properties animation did not work with
copy on write enabled.
The root of the issue is going to the fact, that all interface elements are
referencing original datablock. For example, View3D has pointer to camera it's
using, and all areas which does access v3d->camera should in fact query for
the evaluated version of that camera, within the current context.
Annoying part of this change is that we now need to pass depsgraph in lots
of places. Which is rather annoying.
Alternative would be to cache evaluated camera in viewport itself, but then
it makes it annoying to keep things in sync.
Not sure if there is nicer solution here.

The RenderResult struct still has a listbase of RenderLayer, but that's ok
since this is strictly for rendering.
* Subversion bump (to 2.80.2)
* DNA low level doversion (renames) - only for .blend created since 2.80 started
Note: We can't use DNA_struct_elem_find or get file version in init_structDNA,
so we are manually iterating over the array of the SDNA elements instead.
Note 2: This doversion change with renames can be reverted in a few months. But
so far it's required for 2.8 files created between October 2016 and now.

Practically all access to enum data is read-only.
|
|
2.8x branch added bContext arg in many places,
pass eval-context instead since its not simple to reason about what
what nested functions do when they can access and change almost anything.
Also use const to prevent unexpected modifications.
This fixes crash loading files with shadows,
since off-screen buffers use a NULL context for rendering.
|
|
Note that some little parts of code have been dissabled because eval_ctx
was not available there. This should be resolved once DerivedMesh is
replaced.
|
|
|
|
Also remove duplicate & mismatching comments from grease-pencil header.
Keep comments close to implementation to avoid getting out of sync.

Design Documents
----------------

* https://wiki.blender.org/index.php/Dev:2.8/Source/DataDesignRevised
User Commit Log
---------------
* 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.

When the parent object matrix change after the layer was parented, the
inverse matrix for strokes must be updated when editing strokes or the
transformations will be wrong.
|
|
A common problem encountered by artists was that they would accidentally move
the 3D cursor while drawing, causing their strokes to end up in weird places in
3D space when viewing the drawing again from other perspectives.
This operator helps fix up this mess by taking the selected strokes, projecting them
to screenspace, and then back to 3D space again. As a result, it should be as if
you had directly drawn the whole thing again, but from the current viewpoint instead.
Unfortunately, if there was originally some depth information present (i.e. you already
started reshaping the sketch in 3D), then that will get lost during this process.
But so far, my tests indicate that this seems to work well enough.

working on other stuff

This is a good point to change this as grease-pencil-v2 branch was just merged, so I hope merge conflicts with other branches are minimal.

Improve current Grease Pencil in order to get a better 2D animation tool.

stroke thickness
As soon as you started trying to smooth a stroke, the thickness of the stroke
would quickly drop right down to near zero, if "affect pressure" was enabled.
This step got accidentally missed when restoring the affect pressure functionality to
the stroke smoothing brush code, following cleanups from the stroke quality patch.

Improve the quality of current grease pencil strokes adding a new dynamic smooth and subdivision. The level of smooth and subdivide can be adjusted using UI parameters. These options are disabled by default in order to keep the grease pencil stroke compatible with any existing add-on.
Both parameters are defined at layer level.

This commit merges all the work done in the GPencil_Editing_Stage3 branch
as of ef2aecf2db981b5344e0d14e7f074f1742b0b2f7 into master. For more details
about the changes that this brings, see the WIP release notes:

* Moved the context handling stuff into gpencil_utils.c
* Moved the datablock and layer operators out into their own file too. Again,
these weren't related to the other stuff that much
* Split the GPencil to Curves operator out into its own file (gpencil_convert.c).
This was quite a massive blob of code (48kb) that was not that related to the
other operators still in that file (gpencil_edit.c)
|
|
|
|
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...
