This removes a bunch of animation/driver evaluations and recalc flags that
should be redundant in the new depsgraph, and were incorrectly affecting
the evaluated scene in a permanent way.
Still two cases that could be removed if the depsgraph is improved, in
BKE_object_handle_data_update and BKE_cachefile_update_frame.
For physics subframe interpolation there are also still calls to
BKE_object_where_is_calc that should ideally be removed as well, though
they are not known to cause keyframing bugs.

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.
|
|
Use 'ob' prefix for objects, 'eval' suffix for evaluated data.
|
|
Get current frame from depsgraph, not scene.
|
|
We handle doversion for the scene properties, but not for the
view layer overrides.
Overrides will be implemented in a different way via dynamic overrides.
For now this data is completely lost.
|
|
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.

Same thing for mat3.

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 don't have to re-initialize the full evaluation
context in every area we need it.

This is in order to not mix it with the incomming buffer textures.

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.

TAA / multiple samples is not working at the moment.

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.

Thanks to @sergey for the patch.
Also include some sexy line breaks.

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.

Also move descriptions into doxy header
|
|
This also:
- make sure to only compile the shader needed by the active effects.
- same thing for the shading groups.
- disable TAA if motion blur is active (avoid infinite refresh).
