Experiment: let the user be in control of the alpha channel as some rigs
are hard too see during bone selection. Especially rigs that were
designed for 2.79 wireframe mode.

A cavity shader based on SSAO. Works on all workbench deferred passes.
Per 3d viewport the cavity shader options can be set as different
shading needed different options. Some global options are in the
Viewport Display of the scene like num samples and distance.

The default behaviour is to show the same amount of edges as 2.7.
The slider makes it possible to show all edges or even less.

- users can use their own matcaps
.config/blender/2.80/datafiles/studiolights/matcap/ folder
- upto 100 matcaps can be loaded
- color of the matcap is influenced by the color of the material/single
color etc. To show the plain matcap use single color at 1.0
- chosing a matcap is at lighting level (flat/studio/matcap)
- matcap only possible in solid mode
- also works for X-Ray mode
As the old matcaps are still in used by the clay engine I didn't remove
it yet.

- will not render when set to 0.0 for speed reasons. so when user sets
transparency to hide everything the bigger passes will be skipped.

This commit restores support for Motion Path drawing in 2.8 (as it wasn't ported over
to the new draw engines earlier, and the existing space_view3d/drawanimviz.c code was
removed during the Blender Internal removal).
Notes:
* Motion Paths are now implemented as an overlay (enabled by default).
Therefore, you can turn all of them on/off from the "Overlays" popover
* By and large, we have kept the same draw style as was used in 2.7
Further changes can happen later following further design work.
* One change from 2.7 is that thicker lines are used by default (2px vs 1px)
Todo's:
* There are some bad-level calls introduced here (i.e. the actgroup_to_keylist() stuff).
These were introduced to optimise drawing performance (by avoiding full keyframes -> keylist
conversion step on each drawcall). Instead, this has been moved to the calculation step
(in blenkernel). Soon, there will be some cleanups/improvements with those functions,
so until then, we'll keep the bad level calls.
Credits:
* Clément Foucault (fclem) - Draw Engine magic + Shader Conversion/Optimisation
* Joshua Leung (Aligorith) - COW fixes, UI integration, etc.

This currently shows panels that were in the 2.79 3D view toolbar
which are now popovers.
In some cases it's useful for these to stay open.
This commit adds a space type to do this.
Note this is currently empty in object mode.
|

This overlay is showing mesh topology. It is usable with transparency
even if the mesh order can mess up with the expected result (some object
more prominent than others).
Edge thickness and alpha values are hardcoded for now but can easily be
added to theme or object settings.
|
|
|
|
Also use 'uint'.
|
|
Their purpose is the same, no reason to break API compatibility here.
|
|
This is whats done already elsewhere.
|
|
Added specular highlights for:
- Solid studio shading
- Texture studio shading
|
|
|
|
Initial support for expanding editors, see: T54744
|
|
|
|
Scene lights are rendered when
- v3d is not available
- or shading type is other then OB_MATERIAL
- or shading type is OB_MATERIAL and use_scene_light is true
|
|
The mirror ball and diffuse ball are only rendered when overlays are
turned on and the lookdev overlay is turned on.

- Vertex/Edge Slide: Correct UV's = ON
- Extrude Along Normals: Even Thickness = ON
- Laplacian Smooth: Lambda Factor = 1.0
- UV/Image Editor: Normalized Coordinates = ON
- Render Image: Dithering = 1
- Image Sequence Auto Refresh = ON

* Add horizontal bar at bottom of all non-temp windows, similar to the Top-bar.
* Status-bar is hidden in UI-less fullscreen mode
* Current contents are preliminary and based on T54861:
** Left: Current file-path if needed. "(Modified)" note if file was changed.
** Center: Scene statistics (like in 2.7 Info Editor).
** Right: Progress-bars and reports
* Internally managed as own "STATUSBAR" editor-type (hidden in UI).
* Like with the Top-bar, Status-bar data and SDNA writing is disabled.
* Most changes in low-level screen/area code are to support layout bounds that differ from window bounds.
Design task: T54861
Main changes approved by @brecht.

So it fits in the pop-over
|
|
Unmultiplied the final color during compositing. Same as the revealage
buffer would do
Also use the DRW_STATE_ADDITION_FULL as it is aware of premultiplied
colors
|
|
Option to see through all meshes (transparency)
Works for OB_SOLID and OB_TEXTURED. Does not work for
V3D_SHADING_SHADOW.

OVERVIEW
* In 2.7 terminology, all layers and groups are now collection datablocks.
* These collections are nestable, linkable, instanceable, overrideable, ..
which opens up new ways to set up scenes and link + override data.
* Viewport/render visibility and selectability are now a part of the collection
and shared across all view layers and linkable.
* View layers define which subset of the scene collection hierarchy is excluded
for each. For many workflows one view layer can be used, these are more of an
advanced feature now.
OUTLINER
* The outliner now has a "View Layer" display mode instead of "Collections",
which can display the collections and/or objects in the view layer.
* In this display mode, collections can be excluded with the right click menu.
These will then be greyed out and their objects will be excluded.
* To view collections not linked to any scene, the "Blender File" display mode
can be used, with the new filtering option to just see Colleciton datablocks.
* The outliner right click menus for collections and objects were reorganized.
* Drag and drop still needs to be improved. Like before, dragging the icon or
text gives different results, we'll unify this later.
LINKING AND OVERRIDES
* Collections can now be linked into the scene without creating an instance,
with the link/append operator or from the collections view in the outliner.
* Collections can get static overrides with the right click menu in the outliner,
but this is rather unreliable and not clearly communicated at the moment.
* We still need to improve the make override operator to turn collection instances
into collections with overrides directly in the scene.
PERFORMANCE
* We tried to make performance not worse than before and improve it in some
cases. The main thing that's still a bit slower is multiple scenes, we have to
change the layer syncing to only updated affected scenes.
* Collections keep a list of their parent collections for faster incremental
updates in syncing and caching.
* View layer bases are now in a object -> base hash to avoid quadratic time
lookups internally and in API functions like visible_get().
VERSIONING
* Compatibility with 2.7 files should be improved due to the new visibility
controls. Of course users may not want to set up their scenes differently
now to avoid having separate layers and groups.
* Compatibility with 2.8 is mostly there, and was tested on Eevee demo and Hero
files. There's a few things which are know to be not quite compatible, like
nested layer collections inside groups.
* The versioning code for 2.8 files is quite complicated, and isolated behind
#ifdef so it can be removed at the end of the release cycle.
KNOWN ISSUES
* The G-key group operators in the 3D viewport were left mostly as is, they
need to be modified still to fit better.
* Same for the groups panel in the object properties. This needs to be updated
still, or perhaps replaced by something better.
* Collections must all have a unique name. Less restrictive namespacing is to
be done later, we'll have to see how important this is as all objects within
the collections must also have a unique name anyway.
* Full scene copy and delete scene are exactly doing the right thing yet.

The real reason is that there is a conflict between Carbon header defining
a "Collection" struct, and this works around it.

This patch adds support for:
- Per space-type tools (3D view and edit).
- Per mode tools (object, edit, weight-paint .. etc).
The top-bar shows the last activated tools options, this is a design
issue with using a global topbar to show per-space settings.
See D3395

Disabled shadows for now as the calculation of the light direction is
still to bogus.
|
|
Outline is reserved for the Overlap Overlay
|
|
* Move Shading modes out of the popover
* Move Show Overlays out of the popover
* Test moving the Mode to the topbar again
* Move submode (select vertex, edge, face) to the topbar
* Remove icon from show_manipulator toggle

Pivot variables are now stored in scene toolsettings.

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.

Bone selection overlay is only available in pose mode.
and when active overrules the selection buffer.
This is currently `tricked` by switching the draw engines, but this is
an exception. Not sure how to solve this in a better way.
After this is solved we can look at how to localize the dim effect to only the objects connected to the active armatures. Currently it dims the whole screen (including background).
@campbellbarton I added you as reviewer as it you have done a lot in the DRW_draw_select_loop

Currently set when setting the cursor location,
optionally used as an orientation type.
Intended for use by tools too.

This is half the replacement of the old wireframe mode. It's not doing any
XRay drawing at the moment.
