Scroll-bars are now hidden unless the cursor approaches them, in which case they
smoothly grow and become more & more visible. Note that since 0d309144020168e55,
scroll-bars are drawn on top of editor contents. There's no more jumping of
buttons when scroll-bars appear.
Technical notes:
* AZones are used to adjust scrollbars based on mouse movements
We may want to support screen level AZones if we want scrollbars to also
smoothly appear when approaching them from a different area.
I also plan to make further changes to AZones to clean up stuff a bit.
* Had to move AZone handling to a post ARegion init stage, since we need the
updated View2D data from there.
* View2D masks and scroller rectangles are now updated on every redraw. It's
cheap to do that though.
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.
Initial review of the shard shadows in the workbench engine.
Speed optimizations like transform feedback are not implemented yet. I first want this part to be reviewed and merged.
@fclem please check the note in drw_stencil_set it was holding back nequal == 0 as by default DST.stencil_mask was set to 0. questioin is should we remove the whole check or not.
Also I am still looking for a better name (or split the enum) for DRW_STATE_STENCIL_DEPTH_FAIL_INCR_DECR_WRAP

It's usefull in some scenario to tweak the specular intensity of a light
without modifying the diffuse contribution.
Cycles allows it via lamps material which we currently not support in Eevee.
This is a good workaround for now.
- ability to switch between Single Color, Object Color, Material Color
and Random Color
- fixed Shading and Lighting popover
- Renamed Solid -> Single Color
This commit introduces `EditMeshData`. The fields in this struct are
extracted from `EditDerivedBMesh` into their own struct `EditMeshData`,
which can then also be used by the `Mesh` struct. This allows passing
deformed vertices efficiently to the draw routines.
The modifier code constructs a new Mesh instead of writing to ob->data;
even when ob->data is a CoW copy, it can still be used by different
objects and thus shouldn't be modified by a modifier.
Dynamically sized regions in the topbar were flickering due to only updating
their size after redraws. Now there is an optional layout() callback for
all regions in an area to do UI layout first, then refresh the region layout,
and then do the actual drawing for each region.
Task T54753
For Blender 2.8 we had to be compatible with very old OpenGL versions, and
triple buffer was designed to work without offscreen rendering, by copying
the the backbuffer to a texture right before swapping. This way we could
avoid redrawing unchanged regions by copying them from this texture on the
next redraws. Triple buffer used to suffer from poor performance and driver
bugs on specific cards, so alternative draw methods remained available.
Now that we require newer OpenGL, we can have just a single draw method
that draw each region into an offscreen buffer, and then draws those to
the screen. This has some advantages:
* Poor 3D view performance when using Region Overlap should be solved now,
since we can also cache overlapping regions in offscreen buffers.
* Page flip, anaglyph and interlace stereo drawing can be a little faster
by avoiding a copy to an intermediate texture.
* The new 3D view drawing already writes to an offscreen buffer, which we
can draw from directly instead of duplicating it to another buffer.
* Eventually we will be able to remove depth and stencil buffers from the
window and save memory, though at the moment there are still some tools
using it so it's not possible yet.
* This also fixes a bug with Eevee sampling not progressing with stereo
drawing in the 3D viewport.

The issue was that every object tweak was doing a full copy
of original datablock onto evaluated version, and was updating
animation. This made it impossible to tweak properties which
has keyframes.
Proposed solution is to:
- Always apply animation on frame change, and when object
is explicitly tagged for animation update.
This will store original DNA value of animated property
in the f-curve.
- When applying animation in other cases, we check original
DNA value stored in f-curve with the actual original DNA
property. If they differ, it means user started to tweak
animated property, and we should skip animation.
If the value is the same, we apply animation.
This is just a first step towards proper final implementation,
but seems to be the direction we want to take.
Both the scene and workspace had an active view layer, and it was confusing
which settings were being used or displayed where. Now we always have one,
so there is no mismatch.
The "View Layers" tab in the properties editor is now "View Layer", no longer
showing a list of layers. Instead view layers can be added and removed with
the workspace view layer selector. They are also listed and selectable in the
outliner.
Single layer rendering uses the active view layer from the workspace.
This fixes bugs where the wrong active view layer was used, but more places
remain that are wrong and are now using the first view layer in the scene.
These are all marked with BKE_view_layer_context_active_PLACEHOLDER.
Use render settings and active view layer will be handled elsewhere.
Also change icon to not be confusing with render layers.
Probably we should get rid of the workspace tab entirely and do it in
the user preferences, but that's for later.
Added Object Overlap Overlay
- Added R32UI support to GPU_framebuffer
- Added R32U support to draw manager
- The overlay mode has a object data pass that will render 'needed' data to specific buffers so we can mix them together via a deferred rendering. In future will also add UV's and other data
- Overlap is implemented as an overlay so it could be used on top of the Scene lighted Solid mode (that will be rendered by Eevee.

* "Scenes" now shows for each scene lists of all view layers, collections and
objects contained in it. This is the place to see all collections and objects
in the scene even if they are not used in any view layer. Objects are nested
according to parenting here.
* "Collections" now shows all collections in the view layer, and the objects
in those collections. Objects are not nested by parenting, only collections
since it would be too confusing if the children are in a different collection.
* "Groups" is unchanged.
* "View Layer" was removed, replaced by "Collections".
Part of T54790.
Timelines and Logic Editors are gone. So far they were simply replaced by broken
Info Editors, now they are replaced by Dopesheets in the new Timeline mode.
We reuse ScrArea.butspacetype to temporarily store the space-type identifier of
the deprecated editor (see 9db492de6d). That way we can identify it in
versioning code and replace it nicely.
Action editor creation needs a scene to set the scrolling based on frame range.
Active screen-layouts use the active scene of the window they are displayed in.
Inactive screens simply use the first scene in the main data base.
Note that inactive editors don't need version patching, readfile.c converts them
to SPACE_EMPTY already, so users can't activate them.
Files saved since the editors were removed will still be broken.
Workspace config files saved before this will also crash (will update default
one in followup commit).
The only real reason we need `butspacetype` is while switching areas, where we
need to delay the actual switch to the RNA _update callback since only there we
can access context.
So instead of trying to sync it with `spacetype`, only set while needed and
unset it afterwards (as in set to `SPACE_EMPTY`).
This should also allow us to re-use `butspacetype` in versioning code when
trying to read removed editors. It'll store the space type value of the removed
editor which we can then use on versioning.
For backwards compatibility, we store `butspacetype` with the value of
`spacetype`.
