This makes code closer to id_override/assent-engine ones, which
introduce a new type of linked data, and hence reserve
ID_IS_LINKED_DATABLOCK to real linked datablocks.
GSOC 2017 by Darshan Kadu, see: D2859.
This is a partial merge of some of the features from
the soc-2017-vertex_paint branch.
- Alpha painting & drawing.
- 10 new color blending modes.
- Support for vertex select in vertex paint mode.
Iterate over invisible objects too, so lamps can still lit the scene.
Also, now you can use a collection to set an object to invisible, not
only to visible.
For example:
Scene > Master collection > bedroom > furniture
Scene > View Layer > bedroom (visible)
> furniture (invisible)
The View Layer has two linked collections, bedroom and furniture.
This setup will make the furniture collection invisible.
Note: Unlike what was suggested on D2849, this does not make collection
visibility influence camera visibility. I will keep this as a separate
patch.

Use mesh batch cache for mesh selection.
Note that we could create the batches and free immediately
so they don't take up memory.
This resolves a problem where selection was limited
to immediate-mode buffer size.
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.
We do have an history of those pieces of evil in our code, would be nice
to get fully rid of it, but at the very least let's not add more of them
in new code. :)
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.
Was doing O(n^2) list lookups with blender-render drawing & transform.
Also missing NULL checks would crash.
Use Object.base_flag (already used by new draw manager in places)
to avoid list lookup.
Note, transform still performs inefficient lookups,
but only for selected parents (like 2.7x), not all parents.
Sync with custom-manipulators branch
- Use identifiers for properties.
- Property array index access.
- Remove operator from manipulators
(wasn't used and will likely add in a different way).
Use indirect access to it via object.
It was already flushing from base to object, now we can avoid such flushing.
Still weird to have selection color filled in by dependency graph, but now
there is no synchronization going on at least.
We only keep this as a way to get GPU_stubs to run, in case we want to do a
throughout cleanup in the codebase and want code using legacy calls to
fail to build.
The "Modern Viewport" was an option in the Viewport panel that would use
the new fancy wire frame code and some depth debugging functionality.
This was introduced as a quick and dirty way to get the new drawing
system showing in the viewport.
Overtime we built a complete Draw Manager system, leaving this original
approach deprecated which adds clutter to Blender code since it would be
removed sooner or later.
Note: The new fancy wireframes and related shaders (white out other
objects) are still in Blender code, though you can't use them anymore.
If we are to have any of those drawing options they should be integrated
in the new draw manager, instead of integrated in the old drawing
pipeline as it was originally coded.
