Was caused by a code which was putting animation value back to
original datablock.
The tricky part here is that we don't always know ID, so can not
put those values. Would be nice to have a solution for this, but
for until then we should be relatively good.

Palettes were incorrectly set as having animation data.

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.
You can get more info here:

https://code.blender.org/2018/07/grease-pencil-status-update/
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.

The easy ones - there some much, much trickier to tackle there...
|
|
|
|
Store the compiled expressions on the original driver.
Ref T55442.

Strip unindented comment blocks - mainly headers to avoid conflicts.

They are no longer needed after the active depsgraph concept is here.
|
|
Only do it for active dependency graph.
Currently covers animation, drivers, object and pose channel matricies.
|
|
This way we allow animation system to make decisions based on which
context dependency graph is coming from, and whether it belongs to
an active edit window or not.
|
|
|
|
|
|
Not so important but convenient for testing, and makes the Cycles tests
pass again for now.
|
|
Currently only affects EVALUATION debug messages, rest are to be
supported on per-depsgraph level.

The issue was that every object tweak was doing a full copy
of original datablock onto evaluated version, and was updating
animation. This made it impossible to tweak properties which
has keyframes.
Proposed solution is to:
- Always apply animation on frame change, and when object
is explicitly tagged for animation update.
This will store original DNA value of animated property
in the f-curve.
- When applying animation in other cases, we check original
DNA value stored in f-curve with the actual original DNA
property. If they differ, it means user started to tweak
animated property, and we should skip animation.
If the value is the same, we apply animation.
This is just a first step towards proper final implementation,
but seems to be the direction we want to take.

This way we can re-use reading part.

Brecht authored this commit, but he gave me the honours to actually
do it. Here it goes; Blender Internal. Bye bye, you did great!
* Point density, voxel data, ocean, environment map textures were removed,
as these only worked within BI rendering. Note that the ocean modifier
and the Cycles point density shader node continue to work.
* Dynamic paint using material shading was removed, as this only worked
with BI. If we ever wanted to support this again probably it should go
through the baking API.
* GPU shader export through the Python API was removed. This only worked
for the old BI GLSL shaders, which no longer exists. Doing something
similar for Eevee would be significantly more complicated because it
uses a lot of multiplass rendering and logic outside the shader, it's
probably impractical.
* Collada material import / export code is mostly gone, as it only worked
for BI materials. We need to add Cycles / Eevee material support at some
point.
* The mesh noise operator was removed since it only worked with BI
material texture slots. A displacement modifier can be used instead.
* The delete texture paint slot operator was removed since it only worked
for BI material texture slots. Could be added back with node support.
* Not all legacy viewport features are supported in the new viewport, but
their code was removed. If we need to bring anything back we can look at
older git revisions.
* There is some legacy viewport code that I could not remove yet, and some
that I probably missed.
* Shader node execution code was left mostly intact, even though it is not
used anywhere now. We may eventually use this to replace the texture
nodes with Cycles / Eevee shader nodes.
* The Cycles Bake panel now includes settings for baking multires normal
and displacement maps. The underlying code needs to be merged properly,
and we plan to add back support for multires AO baking and add support
to Cycles baking for features like vertex color, displacement, and other
missing baking features.
* This commit removes DNA and the Python API for BI material, lamp, world
and scene settings. This breaks a lot of addons.
* There is more DNA that can be removed or renamed, where Cycles or Eevee
are reusing some old BI properties but the names are not really correct
anymore.
* Texture slots for materials, lamps and world were removed. They remain
for brushes, particles and freestyle linestyles.
* 'BLENDER_RENDER' remains in the COMPAT_ENGINES of UI panels. Cycles and
other renderers use this to find all panels to show, minus a few panels
that they have their own replacement for.

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.

This way we can easily control format and keep it consistent.
And also possibly do other trickery, like coloring addresses!
|
|
The issue was only visible with copy-on-write enabled, and related to the
fact, that dependency graph builder binds original FCurves.
For now use smallest patch possible to make things to work and to make
draguu happy.
Need to think of a smarter way to deal with drivers, bones and view layers.

Now it's possible to have debug messages for following things:
- Graph construction
- Graph evaluation
- Graph tagging

renaming/fixing code

Conventions were already followed nearly everywhere.

Currently this is a no-visible-changes change, but the idea is to use this
dedicated flag to tell which exact components of ID changed, make it more
granular than just OBJECT and OBJECT_DATA. Allow setting this field based
on what components new dependency graph flushed on evaluation.
|
|
New dependency graph is supposed to have relation from animation node to
the node which corresponds to a property which is modified by that curve.
This means it is up to dependency graph to flush recalc flags, and no
manual control is needed in the animation code.

T52009)
* For the T48988 fix (i.e. separate Ease In/Out properties for Bendy Bones
in Edit vs Pose modes), old animation data needed to be patched to use
the new property names. This is needed to partially fix some of the
issues in T53356 (though the Rigify code itself still needs to be patched).
* For the T52009 fix, old files needed to have the frame_start and frame_end
properties on the FModifier (base-class) updated to match that of the
FMod_Stepped type-specific class. This wasn't done in the earlier commit
since it wasn't worth going through all animation data just for the sake
of updating these relatively-rare settings, but since we're doing it anyway
now, it makes sense to include this here.

it easier to apply fixes to all F-Curves in a file

Previously it was returning short, which was really easy to (a) compare against
non-ID type value (b) forget to handle some specific value in switch statement.
Both issues happened in the nearest past, so it's time to tighten some nuts
here.
Most of the change related on silencing strict compiler warning now, but there
is also one tricky aspect: ID_NLA is not in the IDType enum. So there is still
cast to short to handle that switch. If someone has better ideas how to deal
with this please go ahead :)

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.
