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This is often invalid, outdated or misleading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.

Now it shows more compact info below the view/object name. Render time and
memory usage is left out, as in most cases this is not so important. These
could be added back optionally if needed.

Full redesign of the cache system used for drawing strokes and handle derived frame data.
Before, the cache was saved in bGPdata and a hash was used to manage several objects with the same datablock.
Old design made the use of particles very inefficient and prone to bugs and segment faults, and especially when this was mixed with onion skinning and multiple objects using same datablock. Also, there were some conflicts with the depsgrah logic (the old design was done before despgraph was in place) that made the use of hash not working.
The new design saves the data in the object runtime struct and avoid the use of any hash to find the right data. This improves the speed and reduce a lot the complexity of the code, memory allocation, hash overload and adds full support for particles and reused datablocks.
The particles can reuse the modifiers and shader effects of the original grease pencil object.

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.

GPUFrameBuffers were being free when no context was attached or in the
wrong gl context. This make sure this does not happen again.
You can now safely free any gl resource from any thread (well as long as
it's not used anymore!).

- Change gl_context_mutex to a ticket mutex ensuring interactivity even
when rendering.
- Add DRW_custom_pipeline for using DRW outside of the viewport and render
pipeline.
- DRW_opengl_render_context_*** and DRW_gawain_render_context_*** to use
with DRW_custom_pipeline.
- Add possibility to bypass deferred compilation on demand (not User
demand).
- Add union to access DRWMatrixState members more easily.

This makes tagging much more generic and make the world updates more in
line with the new tagging system (Depsgraph).

Locked selection would still occlude with objects which could not be
selected.

The Studio lights are now loaded from disk. The location is
`datafiles/studiolights` they need to be JPG for now. JPG cannot store
HDRI color range but they are clamped inside the Workbench
engine for speed reason. I didn't select JP2K as it might not be
enabled.
Users can add upto 20 HDRI files. This limitation is inside the
RNA_space.c Currently the icons are calculated when you first open the
selection box for the HDRI's. We could add them to a background
rendering later.
I added 2 test files a sky texture rendered in Cycles and an HDRI from
cloud.blender.org.

For some we may add per object overrides, but for most we plan to keep them
strictly per viewport settings. Display settings from the mesh still need to
be moved here, only collections were done to remove that code.

For Blender 2.8 we had to be compatible with very old OpenGL versions, and
triple buffer was designed to work without offscreen rendering, by copying
the the backbuffer to a texture right before swapping. This way we could
avoid redrawing unchanged regions by copying them from this texture on the
next redraws. Triple buffer used to suffer from poor performance and driver
bugs on specific cards, so alternative draw methods remained available.
Now that we require newer OpenGL, we can have just a single draw method
that draw each region into an offscreen buffer, and then draws those to
the screen. This has some advantages:
* Poor 3D view performance when using Region Overlap should be solved now,
since we can also cache overlapping regions in offscreen buffers.
* Page flip, anaglyph and interlace stereo drawing can be a little faster
by avoiding a copy to an intermediate texture.
* The new 3D view drawing already writes to an offscreen buffer, which we
can draw from directly instead of duplicating it to another buffer.
* Eventually we will be able to remove depth and stencil buffers from the
window and save memory, though at the moment there are still some tools
using it so it's not possible yet.
* This also fixes a bug with Eevee sampling not progressing with stereo
drawing in the 3D viewport.

This caused too many problems syncing object modes
with multiple objects/windows/workspaces, see: D3130 for details.

This refactor modernise the use of framebuffers.
It also touches a lot of files so breaking down changes we have:
- GPUTexture: Allow textures to be attached to more than one GPUFrameBuffer.
This allows to create and configure more FBO without the need to attach
and detach texture at drawing time.
- GPUFrameBuffer: The wrapper starts to mimic opengl a bit closer. This
allows to configure the framebuffer inside a context other than the one
that will be rendering the framebuffer. We do the actual configuration
when binding the FBO. We also Keep track of config validity and save
drawbuffers state in the FBO. We remove the different bind/unbind
functions. These make little sense now that we have separate contexts.
- DRWFrameBuffer: We replace DRW_framebuffer functions by GPU_framebuffer
ones to avoid another layer of abstraction. We move the DRW convenience
functions to GPUFramebuffer instead and even add new ones. The MACRO
GPU_framebuffer_ensure_config is pretty much all you need to create and
config a GPUFramebuffer.
- DRWTexture: Due to the removal of DRWFrameBuffer, we needed to create
functions to create textures for thoses framebuffers. Pool textures are
now using default texture parameters for the texture type asked.
- DRWManager: Make sure no framebuffer object is bound when doing cache
filling.
- GPUViewport: Add new color_only_fb and depth_only_fb along with FB API
usage update. This let draw engines render to color/depth only target
and without the need to attach/detach textures.
- WM_window: Assert when a framebuffer is bound when changing context.
This balance the fact we are not track ogl context inside GPUFramebuffer.
- Eevee, Clay, Mode engines: Update to new API. This comes with a lot of
code simplification.
This also come with some cleanups in some engine codes.

By default select wasn't picking the nearest object,
this could have been fixed by not clearing the depth buffer,
but calling GPU_select_(begin/end) without the binded frame-buffer
caused issues for depth-picking. So move GPU_select begin/end to a
callback.
This also has the advantage that only needs to populate the engines once
to draw two passes.
Note that cycling through objects fails with occlusion queries still,
will fix shortly.

This separate context allows two things:
- It allows viewports in multi-windows configuration.
- F12 render can use this context in a separate thread and do a non-blocking render.
The downside is that the context cannot be used while rendering so a request to refresh a viewport will lock the UI. This is something that will be adressed in the future.
Under the hood what does that mean:
- Not adding more mess with VAOs management in gawain.
- Doing depth only draw for operators / selection needs to be done in an offscreen buffer.
- The 3D cursor "autodis" operator is still reading the backbuffer so we need to copy the result to it.
- All FBOs needed by the drawmanager must to be created/destroyed with its context active.
- We cannot use batches created for UI in the DRW context and vice-versa. There is a clear separation of resources that enables the use of safe multi-threading.

For simplicity we choose to execute the rendering of Opengl engines in the main thread and block the interface.
This might be addressed in the future at least for video rendering.
A drawmanager wrapper (DRW_render_to_image) is called by the render pipeline to set up the Opengl state and then call the specific draw_engine->render_to_image function.

This is a special memory manager that keeps memory blocks ready to send as vbo data.
Since we loose which memory block was used each DRWShadingGroup we need to redistribute them in the same order/size to avoid to realloc each frame.
This is why DRWInstanceDatas are sorted in a list for each different data size.
|
|
This way we can have persistent data accross different calls.

I had to make Eevee draw its scene in the scene pass (before it was doing it
in the background pass). This is not ideal since reference images require
a separation between scene and background.
But it's the best way to solve it now. Clay is working fine.

This replaces dedicated flag which wasn't clean who sets it and who clears it,
and which was also trying to re-implement existing functionality in a way.
Flushing is not currently very efficient but there are ways to speed this up
a lot, but needs more investigation.
|
|
This way it is more clear what is needed to be passed and what is available
in the callback itself.
Thanks Dalai for review and tips about engine type!

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.

Engine is not stored in WorkSpaces. That defines the "context" engine, which
is used for the entire UI.
The engine used for the poll of nodes (add node menu, new nodes when "Use Nodes")
is obtained from context.
Introduce a ViewRender struct for viewport settings that are defined for
workspaces and scene. This struct will be populated with the hand-picked
settings that can be defined per workspace as per the 2.8 design.
* use_scene_settings
* properties editor: workshop + organize context path
Use Scene Settings
==================
For viewport drawing, Workspaces have an option to use the Scene render
settings (F12) instead of the viewport settings.
This way users can quickly preview the final render settings, engine and
View Layer. This will affect all the editors in that workspace, and it will be
clearly indicated in the top-bar.
Properties Editor: Add Workspace and organize context path
==========================================================
We now have the properties of:
Scene, Scene > Layer, Scene > World, Workspace
[Scene | Workspace] > Render Layer > Object
[Scene | Workspace] > Render Layer > Object > Data
(...)

This makes updates for the viewport cleaner and also add the possibility to add a new callback called when the scene is updated.

You can change the amount of samples in the user preferences. You do not need to restart blender to see the effect in the new viewport.
This adds another Multisample Framebuffer and textures (so even more memory required).
It works by blitting the default_fb to the multisample_fb each time the renderer need to render one or more "wire" pass.
It it then blit back to the default_fb so that the rest of pipeline is working as expected.
We COULD lower the GPU memory / bandwidth usage to render everything to the same multisample fbo and change the logic depending on if MSAA is enabled or not, but I think it's a bit too much work for now.

This is supposed to help catch bugs if referrencing stack data out of
the draw loop context.
No change is suppose to happen for users (specially because the changes
here happens mostly on debug).
It includes a change in the logic for render loop, to make sure DST is
not accessed before we enter it - contribution by Campbell Barton.
