Take advantage of 2D functions, rotation about the X Y or Z axis, uniform scale factors.
We no longer need to call gpuMatrixBegin_legacy() before using the new API locally in functions.

Selection loop would draw the selection ignoring xray.
Now draw in a separate pass after clearing the depth buffer,
as with regular drawing.
Also disable depth sorting,
caller can sort the hit-list by depth if needed.
There are now only referenced in:
* drawobject.c
* particle_edit.c
* space_image.c (a single case to be handled on workspace branch)
* rigidbody_constraint.c (to be handled in the following commit)
Updated shader names and code that uses them.
All of these shaders produce round points that are anti-aliased and blended against the background.
These were initially named SMOOTH because they replace glEnable(GL_POINT_SMOOTH). But SMOOTH in shader-land refers to vertex attribute interpolation (like glShadeModel(GL_SMOOTH)).
Using SMOOTH to mean two things is confusing, so we now use AA to mean "the point is anti-aliased".
Things like selection outlines didn't work at all.
Caused by rBc973e8d2da5cf3f.
When splitting up bitflags, the equivalent to `foo->flag & (bar1 + bar2)` is
`(foo->flag1 & bar1) || (foo->flag2 & bar2)`, *not*
`(foo->flag1 & bar1) && (foo->flag2 & bar2)`.
Also, let's please avoid using '+' operator for bitwise operations, a
binary addition is a binary OR *with* cary, which can cause quite some damage.
(and replace more instances of BaseLegacy/scene->base with Base/sl->object_bases)
Still need mouse selection, box selection, and menu selection
Also, there is still a problem with BA_WAS_SEL, at the moment only the
objects centers are highlighted.
To bring this fix a step further we need to address all the BA_WAS_SEL instances, and make sure they follow the new design.
This commit allow you to see the object selected (its center anyways) when you do select all.
Note: in the clay engine selection (a) was already working fine.

User Commit Log
---------------
* New Layer and Collection system to replace render layers and viewport layers.
* A layer is a set of collections of objects (and their drawing options) required for specific tasks.
* A collection is a set of objects, equivalent of the old layers in Blender. A collection can be shared across multiple layers.
* All Scenes have a master collection that all other collections are children of.
* New collection "context" tab (in Properties Editor)
* New temporary viewport "collections" panel to control per-collection
visibility
Missing User Features
---------------------
* Collection "Filter"
Option to add objects based on their names
* Collection Manager operators
The existing buttons are placeholders
* Collection Manager drawing
The editor main region is empty
* Collection Override
* Per-Collection engine settings
This will come as a separate commit, as part of the clay-engine branch
Dev Commit Log
--------------
* New DNA file (DNA_layer_types.h) with the new structs
We are replacing Base by a new extended Base while keeping it backward
compatible with some legacy settings (i.e., lay, flag_legacy).
Renamed all Base to BaseLegacy to make it clear the areas of code that
still need to be converted
Note: manual changes were required on - deg_builder_nodes.h, rna_object.c, KX_Light.cpp
* Unittesting for main syncronization requirements
- read, write, add/copy/remove objects, copy scene, collection
link/unlinking, context)
* New Editor: Collection Manager
Based on patch by Julian Eisel
This is extracted from the layer-manager branch. With the following changes:
- Renamed references of layer manager to collections manager
- I doesn't include the editors/space_collections/ draw and util files
- The drawing code itself will be implemented separately by Julian
* Base / Object:
A little note about them. Original Blender code would try to keep them
in sync through the code, juggling flags back and forth. This will now
be handled by Depsgraph, keeping Object and Bases more separated
throughout the non-rendering code.
Scene.base is being cleared in doversion, and the old viewport drawing
code was poorly converted to use the new bases while the new viewport
code doesn't get merged and replace the old one.
Python API Changes
------------------
```
- scene.layers
+ # no longer exists
- scene.objects
+ scene.scene_layers.active.objects
- scene.objects.active
+ scene.render_layers.active.objects.active
- bpy.context.scene.objects.link()
+ bpy.context.scene_collection.objects.link()
- bpy_extras.object_utils.object_data_add(context, obdata, operator=None, use_active_layer=True, name=None)
+ bpy_extras.object_utils.object_data_add(context, obdata, operator=None, name=None)
- bpy.context.object.select
+ bpy.context.object.select = True
+ bpy.context.object.select = False
+ bpy.context.object.select_get()
+ bpy.context.object.select_set(action='SELECT')
+ bpy.context.object.select_set(action='DESELECT')
-AddObjectHelper.layers
+ # no longer exists
```
This includes a few fixes in the MBC_ api.
The idea here is for this to be the only interface the render engines
will deal with for the meshes.
If we need to expose special options for sculpting engine we refactor
this accordingly. But for now we are shaping this in a per-case base.
Note:
* We still need to hook up to the depsgraph to force clear/update of
batch_cache when mesh changes
(I'm waiting for Sergey Sharybin's depsgraph update for this though)
* Also ideally we could/should use BMesh directly instead of
DerivedMesh, but this will do for now.
Note 2:
In the end I renamed the `BKE_mesh_render` functions to `static
mesh_render`. We can re-expose them as BKE_* later once we need it.

This reverts commit 5aa19be912 and b4a721af69.
Due to postponement of particle system rewrite it was decided to put particle code
back into the 2.8 branch for the time being.
Empty images were implemented to expand (and eventually replace)
the background images functionalities. If we are ever to drop
background images "image empties" should support stereo/multi-view as well.
Consumes much less memory (1/3 for both normals = 32 bytes less per edge). Same visual result.
We can pack normals for other draw modes to get similar savings.
