This commit also provide a compatibility code that will convert old
materials using Additive or Multiply Blend mode to their node equivalent.
This conversion is only done on outputs that are enabled for eevee.
Alpha blended Transparency is now using dual source blending making it
fully compatible with cycles Transparent BSDF.
Multiply and additive blend mode can be achieved using some nodes and are
going to be removed.
This was a read after free error. This only fix the undefined behavior.
The result is still not correct in certain cases (see T67226).
We want to include this for 2.80
Centralize logic for when to use the PBVH for drawing, fix missing tests in
mask drawing, fix missing tests for multiple windows, only do more expensive
update for all viewports at end of the stroke.
This cleans up a bit of duplicated code and some confusion about
what was culled and what wasn't.
Now everything is culled based on the given object pointer.
If the object pointer is NULL there is no culling performed.
This will have multiple benefit.
TODO detail benefits (culling, more explicit, handling of clipping planes)
For now the view usage is wrapped to make changes needed more progressive.
This is to simplify the usage of Volumetrics.
Now it automatically detect if there is any Volumetric material in the
view and allocate the needed buffer if any.
Workbench/Eevee now displays multiple multi-materials correctly.
Iterate over pbvh nodes when doing object iteration. This makes the
rendering process more streamlined and allow for using different materials.
This change will make possible to:
- Add culling pass of each pbvh leaf node. (speedup if zoomed on a small
area)
- Reduce number of lead node iteration.
- Reduce code complexity
Make Lookdev works with bloom and TAA by rendering it before TAA and fixing
the motion vectors of the lookdev balls.
Rework Lookdev to remove much of its complexity. Use simpler matrices with
more understandable setup code.
In final rendering mode the display type was tested for
visibility flag. This should only occus when doing viewport
rendering

This makes it easier to exclude a surface from casting shadows and can be
used to manipulate the shadows even for opaque surfaces.
Versionning ensure that old behavior is transfered to new rendering logic.
