This is a new implementation of the draw manager using modern
rendering practices and GPU driven culling.
This only ports features that are not considered deprecated or to be
removed.
The old DRW API is kept working along side this new one, and does not
interfeer with it. However this needed some more hacking inside the
draw_view_lib.glsl. At least the create info are well separated.
The reviewer might start by looking at `draw_pass_test.cc` to see the
API in usage.
Important files are `draw_pass.hh`, `draw_command.hh`,
`draw_command_shared.hh`.
In a nutshell (for a developper used to old DRW API):
- `DRWShadingGroups` are replaced by `Pass<T>::Sub`.
- Contrary to DRWShadingGroups, all commands recorded inside a pass or
sub-pass (even binds / push_constant / uniforms) will be executed in order.
- All memory is managed per object (except for Sub-Pass which are managed
by their parent pass) and not from draw manager pools. So passes "can"
potentially be recorded once and submitted multiple time (but this is
not really encouraged for now). The only implicit link is between resource
lifetime and `ResourceHandles`
- Sub passes can be any level deep.
- IMPORTANT: All state propagate from sub pass to subpass. There is no
state stack concept anymore. Ensure the correct render state is set before
drawing anything using `Pass::state_set()`.
- The drawcalls now needs a `ResourceHandle` instead of an `Object *`.
This is to remove any implicit dependency between `Pass` and `Manager`.
This was a huge problem in old implementation since the manager did not
know what to pull from the object. Now it is explicitly requested by the
engine.
- The pases need to be submitted to a `draw::Manager` instance which can
be retrieved using `DRW_manager_get()` (for now).
Internally:
- All object data are stored in contiguous storage buffers. Removing a lot
of complexity in the pass submission.
- Draw calls are sorted and visibility tested on GPU. Making more modern
culling and better instancing usage possible in the future.
- Unit Tests have been added for regression testing and avoid most API
breakage.
- `draw::View` now contains culling data for all objects in the scene
allowing caching for multiple views.
- Bounding box and sphere final setup is moved to GPU.
- Some global resources locations have been hardcoded to reduce complexity.
What is missing:
- ~~Workaround for lack of gl_BaseInstanceARB.~~ Done
- ~~Object Uniform Attributes.~~ Done (Not in this patch)
- Workaround for hardware supporting a maximum of 8 SSBO.

This operator converts any stroke of gpencil with a center line into a stroke with the perimeter.
It's possible to assign the active material, keep current or create a new material for all perimeters.
The conversion is only done for strokes with a material using `Stroke`. Only `Fill` strokes are not converted.
Known issues: As the perimter has not boolean implementation, some perimeters can be overlaped. This could be solved in the future when a new 2D boolean library will be developed.

This is temporary to investigate which behavior should be kept when
creating an override hierarchy if there are no cherry-picked data

This removes the 'make override - fully editable' menu entries.
This commit adds visualization to the selection in curves sculpt mode.
Previously it was only possible to see the selection when it was
connected to a material.
In order to obstruct the users vision as little as possible, the
selected areas of the curve are left as is, but a dark overlay
is drawn over unselected areas.
To make it work, the overlay requests the selection attribute and then
ensures that the evaluation is complete for curves. Then it retrieves
the evaluated selection GPU texture and passes that to the shader.
This reuses the existing generic attribute extraction system because
there currently wouldn't be any benefits to dealing with selection
separately, and because it avoids duplication of the logic that
extracts attributes from curves and evaluates them if necessary.

The shortcut for the selection grow is the same we use in mesh sculpt
for the Expand Mask operator (which behaves a bit similar).
This commit contains various new features for curves sculpt mode
that have been developed in parallel.
* Selection:
* Operator to select points/curves randomly.
* Operator to select endpoints of curves.
* Operator to grow/shrink an existing selection.
* New Brushes:
* Pinch: Moves points towards the brush center.
* Smooth: Makes individual curves straight without changing the root

* Puff: Makes curves stand up, aligning them with the surface normal.
* Density: Add or remove curves to achieve a certain density defined

This commit adds a new face nearest snapping mode, adds new snapping
options, and (lightly) refactors code around snapping.
The new face nearest snapping mode will snap transformed geometry to the
nearest surface in world space. In contrast, the original face snapping
mode uses projection (raycasting) to snap source to target geometry.
Face snapping therefore only works with what is visible, while nearest
face snapping can snap geometry to occluded parts of the scene. This new
mode is critical for retopology work, where some of the target mesh
might be occluded (ex: sliding an edge loop that wraps around the
backside of target mesh).
The nearest face snapping mode has two options: "Snap to Same Target"
and "Face Nearest Steps". When the Snap to Same Object option is
enabled, the selected source geometry will stay near the target that it
is nearest before editing started, which prevents the source geometry
from snapping to other targets. The Face Nearest Steps divides the
overall transformation for each vertex into n smaller transformations,
then applies those n transformations with surface snapping interlacing
each step. This steps option handles transformations that cross U-shaped
targets better.
The new snapping options allow the artist to better control which target
objects (objects to which the edited geometry is snapped) are considered
when snapping. In particular, the only option for filtering target
objects was a "Project onto Self", which allowed the currently edited
mesh to be considered as a target. Now, the artist can choose any
combination of the following to be considered as a target: the active
object, any edited object that isn't active (see note below), any non-
edited object. Additionally, the artist has another snapping option to
exclude objects that are not selectable as potential targets.
The Snapping Options dropdown has been lightly reorganized to allow for
the additional options.
Included in this patch:
- Snap target selection is more controllable for artist with additional
snapping options.
- Renamed a few of the snap-related functions to better reflect what
they actually do now. For example, `applySnapping` implies that this
handles the snapping, while `applyProject` implies something entirely
different is done there. However, better names would be
`applySnappingAsGroup` and `applySnappingIndividual`, respectively,
where `applySnappingIndividual` previously only does Face snapping.
- Added an initial coordinate parameter to snapping functions so that
the nearest target before transforming can be determined(for "Snap to
Same Object"), and so the transformation can be broken into smaller
steps (for "Face Nearest Steps").
- Separated the BVH Tree getter code from mesh/edit mesh to its own
function to reduce code duplication.
- Added icon for nearest face snapping.
- The original "Project onto Self" was actually not correct! This option
should be called "Project onto Active" instead, but that only matters
when editing multiple meshes at the same time. This patch makes this
change in the UI.

This commit adds a float selection to curve control points or curves,
a sculpt tool to paint the selection, and uses the selection influence
in the existing sculpt brushes.
The selection is the inverse of the "mask" from mesh sculpt mode
currently. That change is described in more detail here: T97903
Since some sculpt tools are really "per curve" tools, they use the
average point selection of all of their points. The delete brush
considers a curve selected if any of its points have a non-zero
selection.
There is a new option to choose the selection domain, which affects how
painting the selection works. You can also turn the selection off by
clicking on the active domain.
Sculpt brushes can be faster when the selection is small, because
finding selected curves or points is generally faster than the
existing brush intersection and distance checks.
The main limitation currently is that we can't see the selection in the
viewport by default. For now, to see the selection one has to add a
simple material to the curves object as shown in the differential
revision. And one has to switch to Material Preview in the 3d view.

1. Remove ID template in tool header
2. Rename "Add Amount" to "Count" for add brush
3. Add "use pressure" toggles to radius and strength sliders
4. Move strength falloff to a popover
5. Move many "Add" brush settings to popover called "Curve Shape"
6. Move two "Grow/Shrink" options to a popover called "Scaling"
7. Don't display "Falloff" panel in properties when it has no effect

Add a property to the **Shade Smooth** operator to quickly enable the Mesh `use_auto_smooth` option.

The operator is exposed in the `Object` menu and `Object Context Menu`.

Regarding the implementation, there are multiple ways to go about this (like making a whole new operator altogether), but I think a property is the cleanest/simplest.
I imagine there are simpler ways to achieve this without duplicating the `use_auto_smooth` property in the operator itself (getting it from the Mesh props?), but I couldn't find other operators doing something similar.

This commit adds an option to interpolate the number of control points
in new curves based on the count in neighboring existing curves. The
idea is to provide a more automatic default than manually controlling
the number of points in a curve, so users don't have to think about
the resolution quite as much.
Internally, some utilities for creating new curves are extracted to a
new header file. These can be used for the various nodes and operators
that create new curves.
The top-bar UI will be adjusted in a separate patch, probably moving
all of the settings that affect the size and shape of the new curves
into a popover.

This adds support for X/Y/Z symmetry for all brushes in curves
sculpt mode. In theory this can be extended to support radial
symmetry, but that's not part of this patch.
It works by essentially applying a brush stroke multiple with
different transforms. This is similiar to how symmetry works in
mesh sculpt mode, but is quite different from how it worked in
the old hair system (there it tried to find matching hair strands
on both sides of the surface; if none was found, symmetry did
not work).

This allows object extras such as image-empties to be shown in the VR

be useful for architectural walkthroughs and 3D modeling applications.
Since users may not want to see all object extras (lights, cameras,
etc.), per-object-type visibility settings are also added as session
options.
By slightly refactoring the definition of the 3D View object types
visibility panel (note: no functional changes), the VR Scene Inspection
add-on can show a similar panel without duplicating code. When VR
selection is possible in the future, the object type select options can
also be enabled.

auto-iteration property in mask filter
Note: Auto-iteration is still set manually
for increase/decrease contrast. These should
probably become their own operators.
**Relevant to Artists:** This patch adds an option to the Parenting
menu, `Object (Keep Transform Without Inverse)`, and Apply menu, `Parent
Inverse`. The operators preserve the child's world transform without
using the parent inverse matrix. Effectively, we set the child's origin
to the parent. When the child has an identity local transform, then the
child is world-space aligned with its parent (scale excluded).
**Technical:** In both cases, the hidden parent inverse matrix is
generally set to identity (cleared or "not used") as long as the parent
has no shear. If the parent has shear, then this matrix will not be
entirely cleared. It will contain shear to counter the parent's shear.
This is required, otherwise the object's local matrix cannot be properly
decomposed into location, rotation and scale, and thus cannot preserve
the world transform.
If the child's world transform has shear, then its world transform is
not preserved. This is currently not supported for consistency in the
handling of shear during the other parenting ops: Parent (Keep
Transform), Clear [Parent] and Keep Transform. If it should work, then
another patch should add the support for all of them.
